Fixing some things on the gcc-cross-wrapper (libc was not properly added to the

linking path), and with this achieved bash being cross-compilable.
I fixed the few expressions involved in bash building, so they have well stated
native and non-native inputs.

I also tried to cross-build guile, and with this I found a problem in the
actual cross-gcc: it calls the binutils ld, instead of the ld wrapper. This
way, the programs/shared_libraries don't get the proper -rpath.
