It's similar to FreeBSD in that regard, which is also not a GNU
environment as the compiler and toolchain is LLVM.  However the LLVM
toolchain attempt to be command line and output compatible with the
GNU one AFAIK.

FreeBSD.mk also includes StdGNU.mk.  Maybe we want to rename StdGNU.mk
to generic.mk or common.mk?
