    At a minimum please fix the checker to work.

    It doesn't recurse, all of the .h files include drm.h, which includes
    linux/types.h, this is how its meant to work. If the checker does
    recurse then doesn't define __linux__ then fix that. This isn't a bug in
    the drm header files.

    We copy these files as is into a userspace that is shared with FreeBSD,
    the ifdef is the minimum down from about 10 ifdefs 2-3 years ago
    concession we've made.
