a60b328b - build: drop explicit support for pre-Mavericks OS in the default binaries (#37121)

build: drop explicit support for pre-Mavericks OS in the default binaries (#37121) Hypothetically still supported in the build system back to 10.6 or so, though I doubt it has been tested in a long time on such a system. This lets us avoid needing to specify the libc++ explicitly, which makes the build a bit simpler, and can help with building `clang` in our `deps` folder (which may try to to build support libraries for foreign targets, and get confused by these extra flags).
