We could probably set and export PYTHONDONTWRITEBYTECODE in the main
Makefile when doing an out-of-tree build. Or maybe one could play around
with setting PYTHONPYCACHEPREFIX based on O=, though that seems to be
for 3.8+, so probably not everybody has that. Of course neither of those
should be touched by the build system if already set in the incoming
environment.
