I'm not a great fan of requiring the user to mess with their PATH
to get configure to work. Also, the first python on the path
might be the wrong one, and we don't pass PATH from configure
to make so you end up having to make sure you specify it
right in both places.

Plus we already have --with-python, so if you want to drop
it you need to deprecate it first, and you need a justification
that's strong enough to outweigh breaking users' existing
build/packaging setups and scripts...
