Or maybe there is an innovative way to do all of this, that we have
yet to think of.

We do copy files into tools/include at random times which makes sense
for things that aren't uapi, and we are putting bits of uapi there
already so we could just expand the set of files copied there. AFAICT
the only reason we're copying the uapi files at all is that they're
directly in the same include/ directories as everything else and are
always referenced with their uapi/ prefix.

Oh, this sounds like it would work nicely. No more "make headers"
required (hooray!). Instead, the new approach would be "selftests are
allowed to include from tools/include", and then we can just start
copying the files that we need to that location, and gradually fix up
all the selftests.

I really like this, at first reading anyway.

Muhammad, Shuah, others, what do you think?
