1b4e784a0b Fix debuild warnings/errors
- Update .gitignore, do not place .gitignore into directories installed
in bulk
- Remove executable permissions and shebangs from the scripts that are
supposed to be invoked only via ct-ng frontent; prepend them with $(bash).
Despite what showSamples.sh said, it already has some bashisms.
- Remove --with autotools-dev and override dh_update_autotools_config
to avoid having config.{sub,guess} clobbered with older versions
- Install bash completion where Debian (now) expects it
- Update man page to use .\" as the comment delimiter, instead of
undefined macro (."); also, minor text edits.
- Install kconfig.mk without execute permission.
- Remove shell wrappers from 170-localedef-fix-trampoline.patch, we
do not use that for applying patches
- Revoke execute permissions on 210-expat.sh
- Get flags from dpkg-buildflags if available

20a8525e8b Retire CT_CC_GCC_TARGET_FINAL
Make this behavior default in case the core gcc backend is used
for final compiler (i.e., for baremetal configurations). Not
setting this option breaks canadian baremetal configurations,
and not setting it makes little sense at all in any baremetal
configuration (since in baremetal we don't have any libc to begin
with).

d6bf8e2d98 Fix symlinking to multiarch tools on Cygwin
On cygwin, creating both "foo.exe" and "foo" results in 'ln -sf'
returning an error ("File exists"). However, ln silently removes
the "foo.exe" in this case, so an attempt to re-run the same command

Hence, make binutils.sh also create symlinks with .exe prefix,

does not detect and build multilibs by itself.

- Disable parallel builds for mingw-w64 components; until mingw-w64 core
builds clean, I am not trusting it.

- Make the list of tools to build configurable

- Turn on multilib in x86_64 sample.

- Make warnings about tuple less redundant. As in, "one WARN is enough,
no need to shout it three times".

- Messages about various steps/substeps are more aligned with the rest
of the components.

- Use 'make' instead of ${make} to invoke the companion make just built,
if applicable.

has been complaining about /etc/ld.so.conf presence for almost a year
now and I missed that.

After the release, xldd will be modified to query the compiler for
the list of multilibs to search. This would be too invasive change
before 1.23, though.

Note that it may lead to configurations where xldd currently does not
find the libraries (if both DEMULTILIB and CREATE_LDSO_CONF are turned
off). This is not the default setting in Kconfig, though.

dd55349646 Disable Guile in make if building for host in canadian
make's configure uses pkg-config to detect if Guile should be enabled;
on ArchLinux, this picks up Guile from build machine's pkgconfig and then
it fails to compile.

A better solution might be to create a ${CT_HOST}-pkg-config in
buildtools/bin that would report "unsupported" for all packages.
However a quick grep only showed pkg-config being used by GCJ
(not sure if it will build in canadian cross - we don't have any
samples with GCJ) and Blackfin simulator in GDB (Blackfin is not
currently supported by crosstool-ng). Hence, leave such pkg-config
implementation and testing for another day.

8397ad2c1a Fix the build of elf2flt on Cygwin
The -lcygwin -lc actually breaks the build: elf2flt picks up the symbols for getopt/optarg via
<getopt.h> in binutils-X.Y/include, where optarg is declared without dllimport attribute.
Therefore it pulls in getopt() from libc/libcygwin, but since optarg is not prefixed with
_imp__, it is pulled from libiberty. But the object file in libiberty also contains getopt()
thus resulting in multiple definitions thereof.

While there, kill extraneous -ldl passed into configure - configure detects -ldl successfully.

755de234cb elf2flt: use CT_ARCH to set target CPU, not CT_TARGET
CT_TARGET is composed as "${CT_ARCH}${CT_ARCH_SUFFIX}", so CT_TARGET may
become something like "armv7", for example. This is used by the configure
script to set the "CPU" variable in the Makefile, leading to a commad line
containing

    -DTARGET_armv7 -DTARGET_CPU="armv7"

In this case the compilation of elf2flt.c fails with "Don't know how to
support your CPU architecture??". Passsing "CPU=${CT_ARCH}" in the make
command line overrides the configured value and solves the problem.

Alexey Neyman
7a94c81e5b Rework configure logic wrt GNU autotools
Rather than requiring them of a certain version, detect if they are present
(and have sufficient version) and select an appropriate companion tool
otherwise. The reason is that, for example, most recent gettext requires
automake 1.15, but the newest available CentOS has 1.13. Hence, the option
to "upgrade your system" does not apply, and the warning comment above
the companion tools is rather scary.

With this approach, it will work out of the box - either by using the host's
tools, or by building them as needed. Note that the user can still change
the setting in the config.

While there, propagate the new version checking macro to awk/bash/host binutils,
and switch from --with-foo=xxx to officially blessed FOO=xxx: the latter
does not require checking for bogus values (i.e., --with-foo, --without-foo)
and AC_PROG_* macros recognize the corresponding settings without further
modifications. For now, I kept --with-foo=, if only to complain and steer
people to the new way. To be cleaned up after a release.

3dbb576c17 Make companion libs static.
This follows the trend set by 1*.sh scripts that configure ISL, GMP,
MPFR, CLooG, etc. Building with shared libraries presents all kinds
of problems:
- The shared libraries need to be installed into ${CT_PREFIX_DIR}.
- The binaries linked against companion libs need to have proper
RPATH, or they're looking for shared libs in
.build/${CT_PREFIX}/buildtools/lib.
- All libraries must agree as to whether they're built shared,
static, or both. Otherwise, gettext tries to link in static libncurses.a
into a shared library and fails (since libncurses was compiled without
the -fPIC switch and hence contains relocations that cannot be handled
in a shared library).

So this fixes the current mess. If we decide to re-enable building
the companion libs shared, we should probably make this dependent on
a separate suboption of CT_STATIC_TOOLCHAIN.

Add a config loosely based on one reported in the issue 274.

2091c5dd2d Pass FOR_BUILD flags when building the pass-1/2 core GCC.
Current build passes {CFLAGS,LDFLAGS}_FOR_HOST - which breaks canadian cross
(e.g. tried building for x86_64-unknown-linux-uclibc host). This dates
back to the days of yore when CFLAGS were set directly in the do_gcc_core_backend
(and that function is used as the final gcc's backend).

do_gcc_core_backend is now passed with CFLAGS/LDFLAGS to use, so let
the pass-1/pass-2/final-for-build steps pass the appropriate flags.

6c6829a061 xtensa: fix endianness support
To build uClibc correctly we need correct endianness selected in the
crosstool-NG. Xtensa cores may be little- or big-endian, but this
property is static. The toolchain knows the core endianness and doesn't
need options to select it.
Enable ARCH_SUPPORTS_BOTH_ENDIAN and select LE by default. Specify empty
CT_ARCH_ENDIAN_CFLAG so that -m{big,little}-endian don't get added to
the TARGET_CFLAGS, as it's not supported by gcc. Specify empty
CT_ARCH_ENDIAN_LDFLAG so that -EB/-EL don't get added to the
TARGET_LDFLAGS as they are ignored. Select big-endian in the example
xtensa-unknown-linux-uclibc configuration.

This fixes uClibc toolchain build for little-endian cores.

87bfd55b3b Give companion tools some love.
Allow selection of make/m4/... version. Support imports of new versions
via addToolVersion.sh. Import newest versions of the companion tools.

One non-trivial change is the handling of make versions. Existing code
was not handling make companion tool as described (see the previous
commit). However, since most modern systems have make 4.x, that previous
commit made crosstool-ng always build make as a companion tool.

This traces back to the commit dd15c93 from 2014. That commit's log message
says that actually it was 3.81 which broke the build for certain component
(it was originally breaking eglibc, but I noticed it was breaking current
glibc on powerpc64), and introduced an option to force using 3.81 by
"components that really need it". It looks like in 2.5 years we haven't
seen any such components that really need make 3.81, and (given that make
has already had a few releases since 3.81) we're unlikely to see them
in the future.

Hence, the configure check is changed from "exactly 3.81" to "3.81 or newer".
In its current form, configure will accept make 3.80+, and will not require
make as a companion tool for 3.81+. We might want to bump the latter check
to even newer version given the claim from dd15c93. Killed
COMP_TOOLS_make_3_81_NEEDED.

Anyway, I retained 3.81 just in case; ditto for m4 1.14.3, autoconf 2.65
and automake 1.11.1.

488b27f58b Partially revert 6f8e89cb5c.
The referenced commit replaced 'make' with '${make}' everywhere. This is
wrong for at least the utilities that we may build as companion tools
(make, libtool): this will always invoke the version detected by configure
by supplying the absolute path. In other words, the wrappers in
.build/tools/bin are not fallbacks - they are either temporary (in case
a respective companion tool is built) or permanent redirectors.

This is the reason why the PATH= has .build/*/buildtools/bin at higher
precedence than .build/tools/bin; the latter has the versions detected by
configure and the former has the versions built as companion tools.

Revert the rest of the gang (grep/sed/...) for consistency. After all,
we may decide to supply some of them as well (awk, for instance).

3) x-tools/TARGET/bin/TARGET-{ar,as,elf2flt,flthdr,ld,ld.bfd,ranlib,strip}
4) x-tools/TARGET/TARGET/bin{ar,as,elf2flt,flthdr,ld,ld.bfd,ranlib,strip}

where both (1) and (2) are symlinks to (3). This effectively renders
core pass-2 gcc with elf2flt linker unusable.

This patch fixes libexpat detection for gdb-native and
gdb-cross static builds.

For gdb-native build configure should not touch system
/usr/{lib,include} directories while looking for libexpat.
To fix this we pass --without-libexpat-prefix flag
to configure script.

For gdb-cross build configure is allowed to investigate
system /usr/{lib,include} directories, but it does not
hurt to disable this behavior. In this case configure
falls back to -lexpat, which works as expected.

3ebc5d0c1e libc/*.sh: Deprecate libc_check_config step.

uClibc was the only user of libc_check_config step, as well as

Two other clean-ups in uClibc.sh:
- KERNEL_HEADERS check seems to be bogus, this config option is not
  present even in 0.9.30 - which is not supported already.
- SHARED_LIB_LOADER_PREFIX was renamed to MULTILIB_DIR in 0.9.31,

43c303c946 libc/*.sh: handle combinations of multilib root/dir.
Install startfiles for libc variants into the most specific combination
(suffixed sysroot, if applicable + suffixed multi-os dir, if
applicable). Install headers once in every suffixed sysroot (although it
seems that GCC picks up headers from top-level sysroot, GCC manual
claims that sysroot suffix affects headers search path).

In uClibc, this requires a better sanitization of the directory: it
creates symlinks from {sysroot}/usr/lib/{multi_os_dir} to
{sysroot}/lib/{multi_os_dir} and to do so, it counts the number of path
components in the libdir. This breaks if one of such components is `..'
- symlinks contain an extra `../..' then. Since such sanitization had to
be implemented anyway, use it in other places to print more sensible
directory names.

Also, fix the description of configure --host/--target per musl's
configure help message (and its actual code).

82072d0cbc multilib: Determine which options may pass through.
On some arches (e.g. MIPS) the options like -mabi do not work if
specified more than once (see the comment in 100-gcc.sh). Therefore,
we need to determine which of the options produced by <arch>.sh can
be passed to multilib builds and which must be removed (i.e., which
options vary among the multilibs).

This presents a chicken-and-egg problem. GCC developers, in their
infinite wisdom, do not allow arbitrary multilib specification to be
supplied to GCC's configure. Instead, the target (and sometimes some
extra options) determine the set of multilibs - which may include
different CPUs, different ABIs, different endianness, different FPUs,
different floating-point ABIs, ... That is, we don't know which parts
vary until we build GCC and ask it.

So, the solution implemented here is:
- For multilib builds, start with empty CT_ARCH_TARGET_CFLAGS/LDFLAGS.
- For multilib builds, require core pass 1. Pass 1 does not build any
  target binaries, so at that point, our target options have not been
  used yet.
- Provide an API to modify the environment variables for the steps that
  follow the current one.
- As a part of multilib-related housekeeping, determine the variable
  part of multilibs and filter out these options; pass the rest into
  CT_TARGET_CFLAGS/LDFLAGS.

This still does not handle extra dependencies between GCC options (like
-ma implying -mcpu=X -mtune=Y, etc.) but I feel that would complicate
matters too much. Let's leave this until there's a compelling case for
it.

Also, query GCC's sysroot suffix for targets that use it (SuperH,
for example) - the default multilib may not work if the command line
specifies the default option explicitly (%sysroot_suffix_spec is not
aware of multilib defaults).

cc86d80da2 glibc: Build manuals and locales last

27fed7e5f0 crosstool-NG.sh.in: Don't make lots of symlinks to lib folder
For 4 different folders:

${CT_PREFIX_DIR}
${CT_SYSROOT_DIR}
${CT_SYSROOT_DIR}/usr
${CT_PREFIX_DIR}/${CT_TARGET}

.. symlinks from 'lib32' and 'lib64' to 'lib' were created.
This was untidy and incorrect for multilib (the bitness of
the libraries in 'lib32' and 'lib64' will not be the same)
We can not know which folders this toolchain configuration
will require at this time so let them be created on-demand
instead.

Changed by Alexey Neyman: original change removed too much; we
still need to create the default directories because the os
directories are based off them (e.g. `lib/../lib64').

c7da54edf4 glibc: Use common arch call to get multilib targets
The previous patch added the function 'CT_DoMultilibTarget()' to
scripts/build/arch/*.sh.

This patch calls the common function to (currently) get just the target
tuple for the current multilib target.

This patch was originally by: Cody P Schafer

Changed by Alexey Neyman: first, try `gcc -print-multiarch`. If it is
supported, use whatever it reports. Otherwise, fall back to our
guesswork. Move "i486" quirk into glibc.sh, as it is specific to glibc
(e.g. uclibc will need i386, which is what GCC reports).

34ecc718d9 arch/all: Add common function to return multilib target
This code was abstracted out of Cody P Schafer's multilib patch.
It doesn't seem right having architecture dependent code in a
specific libc implementation script. So this patch breaks it out into
scripts/build/arch/<arch>.sh in a function:

  multilib_target_to_build="$(CT_DoArchMultilibTarget 'multi_flags'
'target-in')"

Note that this function gets called on each multilib variant with
different sets of compiler flags supplied in 'multi_flags'. The caller
will first filter the flags so that there is no conflicting flags (e.g.,
no '-m32 -m64') supplied.

Changed by Alexey Neyman:
- make option analysis check specific option rather than match global
  options string as a whole. Moreover, old code did not handle multiple
  options in the same multilib, e.g. '-m64 -mlittle'.
- fixed substitutions in powerpc.sh (*le variants did not match the
  pattern in the shell parameter expansion)
- make s390.sh actually apply the flags it gathered from the options.
- straighten the spaghetti in x86.sh by setting two flags, arch & abi.
  Also, do not depend on "gnu" being the last part - we can have
  '*-uclibcx32', for example.

55879ed1d8 glibc: do not add bogus options
If a multilib configuration contains an endianness option, the
${endian_extra} is set to, for example, 'mb' (note, no dash!). It is
then added to CFLAGS, resulting in bogus flags like 'mb -mb'. But it is
not even needed, as ${extra_flags} already contains the very same
option!

Found by experimenting with multilibs with different endianness on SH,
which still didn't work, but that's another story...

a60946eb24 arch/sparc: better default CPU when targetting Linux
By default, sparc64-*-linux is configured with -mcpu=v9. However,
according to https://sourceware.org/ml/libc-alpha/2005-12/msg00027.html:
    "There is no Linux sparc64 port that runs on non-UltraSPARC-I+ ISA
     CPUs."

v9 is such a "non-UltraSPARC-I+ ISA CPU", so it makes no sense to
default to v9 when targetting Linux.

Change the default to ultrasparc, even though it can suboptimally
schedule instructions for newer SPARC CPUs. See the pending patch:
