[PATCH] Move abilist files into sysdep dirs.

We could put the files into sysdeps/.../nptl/ subdirectories so they'll
apply in an nptl configuration and be missing entirely in a no-nptl
configuration (which should make such a configuration fail make check,
which seems fine).

But as Dave and Joseph say, we can also just let the next person to build
such a configuration worry about the subject.

I guess my pedantic preference would be to use the nptl/ subdirs.
But I won't argue strenuously if the people doing the actual work
have the contrary preference.

(I do think it's wiser to use sysdeps/.../nptl/ rather than
nptl/sysdeps/... for any new thing.)


Thanks,
Roland
