My inspiration here has been tools/testing/selftests/memfd/Makefile,
which does it this way. If I only include the ones on usr then it
doesn't build, as there's no sync_file.h available, even after running
make headers_install. How am I supposed to use the ioctls from there?
The dma-buf include path is a leftover from the previous version,
there's no longer any headers there. I've fixed the other things you
pointed out, the new Makefile is below if you want to take another look.
Thanks for the review! :)
