Why not?  Would it cause problems?

Is libgcc from GCC 4.6 incompatible with /lib/libgcc?

If I understand correctly, the libgcc in base is pretty stripped
down compared to "regular" libgcc, because most of that
stuff is in our libc instead.  So if there were compatibility
problems, I'd expect those to show up when GCC 4.6 linked
programs against /usr/local/.../libgcc and /lib/libc.
