On the other hand, that answer is not back-patchable, and we surely
need a back-patchable fix, because people will try to build the
back branches against newer pythons.

Based on the buildfarm results so far, the problem can be described
as "some installations say /usr/local when they should have said /usr".
I experimented with the attached delta patch and it fixes the problem
on my Debian 9 image.  (I don't know Python, so there may be a better
way to do this.)  We'd have to also bump the minimum 3.x version to
3.2, but that seems very unlikely to bother anyone.
