To properly enable LTO with gold, gcc has to install a plugin that gold
uses to handle the LTO information.

When both gold and ld are installed, add a wrapper that calls
to either gold or ld.
In case the wrapper is installed, we also need to symlink ld.bfd
and ld.gold for the core_cc steps.

gold is a new, optimised, multi-threaded linker with support
for plugins.
Add support for gold starting with binutils 2.21. Although 2.20
also had gold, the configure flags have changed, and supporting
2.20 would be a mess in the code.

libelf is used by gcc to build the lto-plugin used
by binutils' gold to perform LTO.
This requires that files in libelf be compiled with
-fPIC to generate a proper .so.

Like rev 2002, eglibc installs some bash scripts, but use the path to the
buildtool bash as the interpreter (on the shebang line). This is only a
symlink to the real bash, and thus is not available at runtime.
Fix that by assuming that shell on the target *will* be /bin/bash.

It appears, that the configure scripts of libelf versions 0.8.13 and
0.8.12 do not honour the --host option. The compiler must be given as an
environment variable or the process will use the command "gcc" as the
compiler.
It seems that this is already done in the function do_libelf_target in
scripts/build/companion_libs/libelf.sh, but not in function do_libelf.
Building non-threaded glibc has been unsupported for a long time, now:
http://sourceware.org/ml/libc-alpha/2005-08/msg00091.html
As eglibc is a spin-off of glibc: ditto.
So do not offer that possibility in the menuconfig.
Thanks to Thomas Petazzoni for spotting, and helping to solve, the issue!

Do not try to strip any script.
Previously, only shell scripts were ignored, but when the Java frontend
is installed, it also installs a Python script. So we have to ignore
any "script text executable", and not restrict it to "shell script text
executable".

Download to an intermediate temp file, and rename it to its final
name only of download succeeds.
This catches both a failed download, and also the case where the user
interrupts the download. Thus, the a partial download gets discarded,
and we no longer try to extract a partial tarball, which we would
previously have done.

For 4.3 or before, we have to play some tricks:

(we expect it in ${sysroot}/usr/lib/libc.so)
- trim /usr/lib/libc.so from the result
