Sigh, the out-of-tree build is always making things unnecessary
difficuilt. I have no idea why the directory is not created in the build
tree.

Not at all, this is very different problem :-). Now it fails to build in
these tests that actually use the library. So original problem was fixed
and this is quite possibly wrong config guards used in the tst_numa.c.

I do use ifdef HAVE_NUMA_H in the library in the library and tests it
should be probably replaced by HAVE_NUMA_V2.

Still I would say that the original patches should be pushed and that we
should deal with the rest of the problems in separate ones.
