3330ad7197 Fine-tune moving gcc libraries to sysroot.
1. Check if anything was installed outside sysroot; on some [baremetal only?]
configurations GCC doesn't install anything to ${CT_PREFIX_DIR}/${CT_TARGET}/lib.
2. We need to create <sysroot>/lib/<multilib> if it doesn't exist
(MUSL only installs in <sysroot>/usr/lib).
3. Do not move the linker scripts; elf2flt expects to find them
in gcc's dir, not sysroot.

8121be5b21 Fix m68k with uClibc-ng >= 1.0.15.
1.0.15 only kept a single LINUXTHREADS option, and renamed it, making it
no longer option-compatible with uClibc.

The option for "1.0.14 or later" version of uClibc-ng is not currently
used; rename it to "1.0.15 or later" and use it to handle newer
uClibc-ng's linuxthreads.

m68k happens to be the only sample using linuxthreads.

10972baa20 binutils: make symlinks in a consistent way
On the stage "core gcc pass-2" the following layout is created:

1) buildtools/bin/TARGET-{ar,as,elf2flt,flthdr,ld,ld.bfd,ranlib,strip}
2) buildtools/TARGET/bin/{ar,as,elf2flt,flthdr,ld,ld.bfd,ranlib,strip}
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.

5d5465307b debug/gdb: properly link with expat
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.
This step was only used in uClibc. However, with upcoming multilib, the
config management will have to be done for each variant differently,
anyway.

uClibc was the only user of libc_check_config step, as well as
CT_CONFIG_DIR directory. Retire these.

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,
  according to ChangeLog - and MULTILIB_DIR is passed from command line
  instead.

- Analyze thus combined flags to determine --with-fp/--without-fp.
  Don't need to check CT_ARCH_FLOAT - it is reflected in
  CT_TARGET_CFLAGS anyway. Check more soft/hard float options defined
  on different architectures.
- Drop checking for endianness flags: they are not reflected in
  configure arguments in any way, and they're already present in CFLAGS
  (either via multi_flags or via CT_TARGET_CFLAGS). Besides,
  CT_ARCH_ENDIAN_OPT was actually called CT_ARCH_ENDIAN_CFLAG, so this

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).

.. 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.

still need to create the default directories because the os

c7da54edf4 glibc: Use common arch call to get multilib targets
The previous patch added the function 'CT_DoMultilibTarget()' to

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.

a60946eb24 arch/sparc: better default CPU when targetting Linux
By default, sparc64-*-linux is configured with -mcpu=v9. However,

    "There is no Linux sparc64 port that runs on non-UltraSPARC-I+ ISA

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:

2162cbbdb7 Work-around another quirk in GDB configure.
Previous fix for cross-gdb broke powerpc-unknown_nofpu-linux-gnu which
uses an old GDB (6.8a). That GDB's configure chokes on $CC values with
multiple consecutive spaces; see the comment in 300-gdb.sh.

62d357d3c0 Unbreak static cross-gdb.
GDB's configure mishandles the libexpat.{so,a} libraries when it is
given -static in CFLAGS AND --with-libexpat-prefix in configure's args:
it checks for <prefix>/lib/libexpat.so and finding that, attempts to
link it as `gcc -static .. conftest.c <prefix>/lib/libexpat.so`; this
obviously fails (.so cannot be statically linked), so configure assumes
libexpat is unusable. Thus, --with-libexpat-prefix is dangerous and
should be avoided; instead, configure should find the libraries via the
supplied CC/LD definitions.

9820e4eea5 musl-libc: Rewrite musl.sh build script
This commit moves the do_libc_configure function to do_libc_backend and
switches do_libc_start_files and do_libc_final to call do_libc_backend.

The major reason for the rewrite is that musl => 1.1.13 has had it's own
build system rewritten and can now build out-of-tree.

ec9af46847 glibc: Mirror extra_config flags from do_libc_backend_once
In do_libc_backend_once:
```
              # Also, if those two are missing, iconv build breaks
              extra_config+=( --disable-debug --disable-sanity-checks )
```

But in do_libc_locales we only add ```--disable-debug```.
This change adds ```--disable-sanity-checks``` to do_libc_locales to
mirror this, as I've seen iconv break this way.

644522fcd0 libiconv: configure with --disable-nls
On Windows a build failure can be triggered during the
build of the static iconv if a dynamic iconv is already
present:

There's a circular dependency between libiconv and gettext
which (on a system with a dynamic gettext (and thus iconv)
installed in the system prefix) causes a failure to build
iconv.exe statically if it is built with nls ..

.. Which needs gettext
.. which depends on libiconv
.. so libtool finds a dynamically linked libgettext.la
.. and therefore presents ld with the dll import library
     libiconv.dll.a when linking iconv.exe
.. as well as the static libiconv.a that it has just built!
.. leading to multiply defined symbols from iconv.

Therefore, we build it without nls. If it later turns out
that we need it to be built with nls, then I will have to
build it in two passes (common practice when bootstrapping
GNU/Linux distros, MSYS2 and probably Cygwin and Homebrew).

44ee416289 expat: Tidy up and correct configure flags
Build shared builds for host unless CT_STATIC_TOOLCHAIN.
In all other situations, build statically, as before.

It is necessary that the static/shared-ness of expat matches
that of gettext on Cygwin/MinGW-w64 as they can't be linked
together if they don't match, so we follow the same logic.

1b31314488 CT_GetCustom: Rewrite function to meet expectations
The previous version of CT_GetCustom was a bit... funky.
It didn't handle custom versions to location very well.

This new version is exactly as it appears:

CT_GetCustom <name> <version> <location>

The name is the beginning of the archive (file or directory).
The version is the second half of the archive.
The location is where it can be found. This should be made an absolute
path, but this version is expecting the path in kconfig to be absolute.

A file should extract to a directory: <name>-<version>
A directory will be copied to: <name>-<version>

This keeps our expectations of what we should get.
