Which kind of wireframe model you would require being made for this?

Ok, you must understand that an x86_64 system is 'bi-arch', the GCC
on it should be capable to produce both 64-bit and 32-bit executables.
If the existing GCC cannot do this, neither the new GCC can do that !

So before starting to build the bi-arch GCC (as the default), you should
make sure that both 64-bit and 32-bit executables can be produced on
your system with the existing GCC. That you have the '*/lib64' and the
'*/lib' directories filled with the proper libraries is one of the
prerequisites.

If you want your new GCC to be a "64-bit-only" special GCC, just use
the '--disable-multilib' option during the GCC compile, then no 32-bit
'libiberty' and 'libstdc++-v3' will be tried to be made...
