I don't think that's warranted. The existing design is that we let
the user say which python is "python", and I do not think we should
change that in advance of actually dropping python2 support.

I was wondering about simply probing to see if python3 exists (and if
so, what version it is exactly), as an additional configure test that
doesn't hook into anything. That would give us some information without
suddenly changing what is being tested.
