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

complibs/libelf: use host compiler

It appears, that the configure scripts of libelf versions 0.8.13 and

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.

libc: hide no-thread for those C libraries that do not support it

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.
