So to be more hermetic, I'd like to get to the point where we encourage the user to build the kernel headers from source BEFORE building llvm-libc, then provide those headers.

That way we don't look in /usr/include AT ALL.

For example, I'm not sure that the kernel headers on the host are ok to use when cross compiling.
