I really can't answer that one.  The people who care about
NUMA would have to do that.  It just shouldn't be possible
to make a config with a build error like this.

OK, I prefer option 2 because it is more generic (not hardware-
specific).  Someone else can prefer option 1 because it is
hardware-specific.  :)
