The right way is to use a --with-blah (--with-numa ?) to enable to
feature and then have configure check for the presence of that dev
library and headers. The configure should fail if they are not found.
Hmm, it might be --enable-numa, its a but unclear.
--with--blah means link with library blah, --enable-blah means turn on
feature blah. It's sort of both so perhaps doesn't matter.
The packagers then ensure that if they have enabled this feature that
they pull in the required library (Debian does this with dpkg-shlibdeps
which is run at build time)
