You can't automatically locate python2 on a system that does not have
python2 but only has python3! The correct behaviour is therefore to check
for his own version numbers in the configure script (which petsc already
does to some extent) and put the check right there where users can see it
and read the error message and do something about it if things go wrong
(ie, for now, go install python2 and call that version directly).
