91c192e318 Always build ncurses-for-build
If the build machine lacks tic, we need to build it in the first pass
even if host==build: ncurses Makefiles are not smart enough to build
'tic' first and use the just-built tic to compile fallback terminfo.

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
manually then succeeds.

Hence, make binutils.sh also create symlinks with .exe prefix,
using the new & shiny routine.

7111f95dc3 MinGW-W64 fixes
- libpthread requires iteration over multilibs, unlike the core, it
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.

a596ec5b39 Fix up the sysroot issue for sh4 in a different way
(see the comments in the code for details on the issue)

Old workaround in 100-gcc.sh stopped working (probably, due to one
of GCC version upgrades), so switch to the other approach originally
described there: adjust the list of multilibs to not include the
default target explicitly.

3d1678a7f6 Make creation of ld.so.conf optional
... enabled by default for multilib and disabled otherwise. Buildroot
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.

63b2a19de4 Add an option to "demultilib"
It turns out buildroot does not currently accept a toolchain where a dynamic
linker does not reside in the multi-os-directory. Unfortunately this is
how glibc installs itself on AArch64 without any extra tricks.

So, provide an option to force everything into /lib or /usr/lib; patch to
buildroot will be worked on separately.

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.

3e94b4f680 Skip building locales on macos, too
--enable-hacker-mode is not sufficient, in 2.25 configure then
fails while checking for sysdeps fragments that apply to a given
configuration, and with that worked around, fails on binutils &
compiler version check.

In brief: if someone wants locales on cygwin/macos, you'd have to
implement cross-localedef (similar to cross-rpcgen) in glibc and
submit it upstream.

c88621f740 glibc: hide native c++ executable from build
If glibc's configure finds the host c++ executable it assumes that
c++ should be enabled for the build. In case we don't have cross g++
built yet (ie, for headers), this causes the build to fail creating
C++ headers. So hide C++ from the build.

2dae1cf816 Require GNU sed
After much struggling with macos (BSD) sed and even getting everything
work in crosstool-ng itself, I had to abandon that because some
components rely on GNU syntax. Specifically, GNU libc uses '/.../{H;g}'
(note absense of the separator after 'g').

So, revert the -r/-E detection and check for sed's being of GNU origin.
MacOS people, sorry, but you'd have to install GNU sed.

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.
