Set CC to clang++

[Steven Smith]

I’m trying to build jsonnet <https://github.com/google/jsonnet> (dependency of a larger project).

jsonnet fails to build on macOS with the exact same error others observe, e.g. <https://github.com/anguslees/rust-jsonnet/issues/2>.

If the CC=clang++ hack thing doesn’t work, I’l just commit the whole project and show the error in the build bot.
