Fix building x86_64 on x86_64 (and hopefully all other *64 archs on the same *64):
- symlink all lib64/ dirs to the corresponding lib/ dir
Also, prevent gcc from installing some of its target libs outside of the sys-root, in the first place.
Thanks to Laurent DUFRECHOU for reporting the bug and testing the fix.
