I think Reid tried to fix this in r213180 by passing the --target flag
to this test.

But it's still failing further down, e.g.
http://lab.llvm.org:8011/builders/clang-ppc64-elf-linux2/builds/15641/steps/check-all/logs/Clang%3A%3Acl-x86-flags.c

We could sprinkle more --target options in there, but it's starting to
look weird when we're passing both a --target and /arch: flag, for
example. Maybe we can make lit support REQUIRES: x86-default-target?
