I was just about to do something similar, so I'm glad you got to it before me.

I think we'll need a CMake check on whether or not `libc` was enabled as a runtime if this option is enabled in `libcxx`, but beyond that it looks very reasonable. All we're doing is suppressing the system includes with `-nostdlibinc` and then adding an interface include to the `libc` targets.
