gcc-cross-intermediate: Ensure we move the libraries from the correct location

This fixes multilib issues if you try for example to use a BASELIB of /lib32
which wouldn't work without this change since the compiler install location
is taken from gcc -print-multi-os-directory which can still turn out to be
"/lib".

The reason is that a 32 bit gcc has no multilib code enabled and will always
return "." as that value rather than "../${base_libdir}" which our changes
to gcc enable and return in 64 bit mode.
