Notable changes:

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.
