I agree with Kostya that no major changes to mach_override are necessary
because we are really going to dump it. However minor fixes required for ASan
in GCC to work on Darwin right now should be perfectly ok.

As there currently are issues blocking the dynamic ASan runtime (e.g.
https://code.google.com/p/address-sanitizer/issues/detail?id=124), and we still
depend on CoreFoundation I can't promise that we'll get rid of mach_override
before the GCC 4.8 release.
