For mips64-linux-gnuabi64 the backend emits the direct call to libc's
_flush_cache so the __clear_cache is never used. This test invokes
__clear_cache explicitly, but there is another issue in that llvm will use
__clear_cache libcall for __builtin___clear_cache on mips, so it won't work
unless you ship/link the compiler_rt along with it.

To clarify, the correct behaviour is implemented, it just doesn't get expanded
in libgcc for header reasons.
