r193601 - Teach the driver to not try to use 'lib32' multilib spellings on ARM

They don't break it. They *are* redundant and they do make it harder
to compare clang's behavior with gcc's.

If we don't care about printing paths as gcc does, why are we even
adding things like "lib/.." and printing redundant search path?

Cheers,
