This should be fixed properly using my patch to filter -rR or similar.

That is also wrong. It should *not* be looking in include/uapi.

If it needs headers then it should be using the *exported* headers, which are
in ../../../../usr/include as the existing CFLAGS specifiy.

Those headers are installed as part of 'make headers_install'.
