I see this same code on mainline.

Offhand I'd say that it shouldn't be possible for either of these to
be empty. How is that happening?
It is hard to read configure but it looks to me like these are
unconditionally computed; look around line 645. For debugging, in
case you need to know :), I'll often edit in a 'set -x'/'set +x' pair
to see what is really going on...
