On Darwin, the last argument to GCC is coming up as an empty string. This is breaking the build of proto_library targets. However, I was not able to reproduce with the example cpp project[0]. This commit patches the cc_wrapper of Bazel that gets installed on Darwin to remove the last argument if it's an empty string. This is not a probem on Linux.
