Title: Pidof: Xcode-only fix and uses llvm

Pidof hardcodes the usage of gcc. For xcode-only, we have to pass the CFLAGS. gcc cannot handle some `-march` compiler switches from clang. By making it explicit, the CFLGAS are prepared for llvm-gcc.

I have added a `fails_with :clang` and `build :all` because it is independent of a certain build number. It works but is that the recommended way?
It's also possible to use `EVN.llvm` instead of the "fails_with" thing.
