Does this affect being able to build tools/testing/selftests/futex/ without having to do the ludicrous batshit 'make headers' thing? If I cannot build the futex selftests in a virgin tree, then they're broken. The selftests maintainers have time and time again shown their incompetence and I'm sick of it.
