Yes, libFuzzer does not build on OSX today.
Marshall (CC-ed) has managed to make it work with a couple of #ifdefs
in FuzzerTraceState.cpp.

I'll try to commit such patches later this week, but I don't have a Mac so
it will be harder for me to test.
If anyone wants it quicker -- patches are welcome.
I would also appreciate if someone can set up a build bot for libFuzzer on
Mac :)
