Teach the driver to not try to use 'lib32' multilib spellings on ARM
which doesn't use that multilib. As a consequence, fix Clang's support
for cross compiling environments that were relying on this quirk to
ensure the correct library search path ordering.
This also re-instates the new test cases from Rafael's r193528 for
cross-compiling to ARM on Ubuntu 13.10 without any of the changes to the
existing test cases (they were no longer needed).
This solution was the result of a lot of IRC debugging and trying to
understand *exactly* what quirk was being relied upon. It took some time
for me to figure out that it was the use of 'lib32' is a multilib that
was throwing a wrench in the works.
In case you are thinking that its silly to use a multilib of 'lib' at
all, entertainingly, GCC does so as well (you can see it with the
.../lib/../lib/crt1.o pattern it uses), and the 2-phase sequence of
search paths (multilib followed by non-multilib) has observable (if
dubious) consequences. =/ Yuck.

Revert "Support cross linking to arm on ubuntu."
This reverts commit r193528 (and fixes).
It broke Chandler's setup.

Support cross linking to arm on ubuntu.
With this patch we correctly determine that ubuntu's ARM tree is not biarch
and use "lib" istead of "lib32".
Without this patch the search inside the arm tree for the crt files was failing
and we would end up trying to use the i686 ones in lib32.
