Chandler Carruth da797048d9 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. llvm-svn: 193601		2013-10-29 10:27:30 +00:00
