Of course, both the rsplit and the TargetRegistry::lookup don't work as
expected. Attached patch makes sure that a bare clang actually works.
This still has the problem that e.g. x86_64-netbsd-clang-cpp doesn't
work as expected (at least for me), since TargetRegistry::lookup happily
accepts "x86_64-netbsd-clang" as triple. One option would be to move to
a different separator (e.g. ::). Suggestions?
