Dan Peebles 3263d02626 xcbuild: assorted fixes and cleanups ... 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.		2017-03-21 23:22:15 -04:00
