There's no plan, but that's certainly possible if multiple people keep
facing this issue.
Ideally, I'd rather have configure disable libnuma automagically when
it's needed statically and only available dynamically. But I don't know
how to do that.
We're talking about doing a hwloc 1.3.1 before christmas. I'll see if I
can work on this, and provide some backport patches for 1.2.2.
