This is in preparation for the LLVM 4 upgrade (which gets more strict about e.g., return false in xcbuild itself) and also for using xcbuild more extensively in the Darwin stdenv bootstrap process, which is why I killed the unnecessary gcc dependency in the toolchain. llvm-cov pretends to be gcov anyway, so we're fine.
