Here is an alternative to the patch changing a file imported from
compiler-rt upstream, so that we don't need to cary a local patch for that
particular problem.

Bootstrapped/regtested on x86_64-linux and i686-linux (verified that
-DUSE_SYSTEM_MD5 is passed only when compiling
sanitizer_platform_limits_freebsd.cpp) and Gerald in the PR said
it passed bootstrap on FreeBSD as well.

Ok for trunk?
