Use %clang_cc1 so that the test works even if the target isn't available.

Xcode-style clang builds only support Xcode's architectures, so mips
isn't available and the driver tries to use gcc instead. cc1 will go
ahead and do -fsyntax-only for any platform it knows about even if it
can't actually compile.
