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.

mingw-gcc searches for include and libs in <sysroot>/mingw
directory while non-mingw-gcc uses <sysroot>/usr. This patch
sets an appropriate prefix for target companion libs.

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.

Currently the broken file is not installed when doing an non-local install.
This causes ct-ng list-samples to not notify the user that a sample is
broken. This commit triggers the creation of the broken file as needed.

This change adds native ldd and ldconfig utils to sysroot.
For glibc just 'make install' installs everything including utils.
For uclibc there exists a separate goal 'install_utils'. Make it.

For a cross-compiler, we only need to make the 'build tools' for the
'build'. We also build the 'build tools' for the 'host' when building a
cross-canadian toolchain.

No threads (uclibc/libpthread does not compile on ARMv8); no C++ (libitm
depends on pthreads), no GDB/DUMA (depend on threads).

Based on the following samples:
- x86_64-unknown-linux-gnu (-m64/-m32/-mx32)
- powerpc64-unknown-linux-gnu (-m64/-m32)
- mipsel-unknown-linux-gnu (-mabi={32,n32,64})
- sh4-unknown-linux-gnu (-m4/-m4a)
- x86_64-unknown-linux-uclibc (-m64/-m32)
- mips64el-unknown-linux-uclibc (-mabi={32,n32,64})
New samples:
- sparc64-multilib-linux-gnu (-m64/-m32)
- sh4-multilib-linux-uclibc (-m4/-m4a/-m3)
- x86_64-multilib-linux-musl (-m64/-m32)
Notably missing is arm-unknown-linux-gnu (aprofile): GLIBC does not
compile in one of the variants in its multilib set (-march=armv4t
-mthumb) due to missing atomic ops implementation.

It turns out that core GCC on binfmt architectures (m68k, for example)
cannot produce the final executable (looks for ld.real in the wrong
place). Need to wait for the final gcc to become available.

'ld' does not search for dependency libraries in multi_os_directory, so
if there's both multi_os_directory and multi_root, and there is only one
configuration in each multi_root, forgo the multi_os_directory suffix.
Needed for sh4-multilib-linux-uclibc.

Create a separate 'libc_backend_once', install headers into a
subdirectory (different sets of headers are installed for 32- and 64-bit
architectures), and create a symlink for the dynamic linker location
expected by GCC.

Rather than echo-ing the new value, set the value into the variable with
the name passed as an argument (similar to CT_SanitizeVarDir). This
allows to use CT_DoLog in these functions.
