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.
