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.

GCC does not distinguish the resulting binary by the CFLAGS (e.g. based
on which -march= was given). This means, while it will use the right
libraries for linking, at runtime they are all going to request the same
ld.so path and load the libraries from the same default path.

Also a fix for CT_IterateMultilibs: it didn't pass multi_os_dir_gcc, so
it only worked if the caller did *not* declare it as a local variable.

Convert absolute targets to relative so that they are valid on the host,
too. The procedure is very similar to uclibc, so it is moved into a
common function.

... and in addition to final toolchain aliasing, use it when configuring
multilibs for glibc/musl. Note that uClibc does not need it, it is
explicitly selecting the tools using CROSS_PREFIX.

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.

... which fails to compile due to incompatible prototype for strlcpy()
which isn't even used.
2.6.33 dropped the prototype, so the patch is n/a for newer kernels.

It picks up gettext string and results in [ERROR] messages from ct-ng
when gettext strings happen inside an error() call.

--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.

The latter does not prevent zlib's configure from overriding 'AR' with
/usr/bin/libtool on macos, and that breaks canadian crosses.

GMP's configure script tries to be too smart, and if it determines
that it's not cross-compiling it chooses gcc or cc instead of the
wrapper we create at the start of the build.
