debug/ltrace: fix building for mips

ltrace 0.5.3 currently fails to build for target mips because MY_TARGET
(introduced by patches/ltrace/0.5.3/150-allow-configurable-arch.patch)
is set to 'mips' via CT_ARCH, while the mips specific stuff in ltrace
(0.5.3) is stored under sysdeps/linux-gnu/mipsel:

result: *** No rule to make target `mips/arch.h', needed by `sysdep.h'.
Stop.

The following patch fixes this issue

Notable changes:
- uses binutils 2.21, builds gold, but defaults to ld
- uses gcc 4.5.2, with GRAPHITE and LTO, builds lto-plugin

cc/gcc: build lto-plugin if binutils' gold is built

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

binutils/binutils: add wrapper to gold and ld

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.

binutils/binutils: add support for threaded gold

When configured with support for threads, gold can link in
parallel, possibly cooperating with a make jobserver.

Add an option enabling threads.

binutils/binutils: add option to enable gold

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.

complibs/libelf: build with -fPIC

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.

libc/eglibc: fix installed scripts

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.
