Specify -stdlib=libc++ if APPLE
If you specify any --target which refers to a x86_64-apple-darwin
triple, or a more specific variant derived from it, specifying
-stdlib=libc++ is required, otherwise clang falls back to libstdc++
which didn't include c++11, and fails to compile in very obscure ways
(simply failing to find any c++11 symbols).
