This reapplies the changes made with 5189c08 that are still needed for

* m4/ax_python_devel.m4: Do not emit 'HAVE_PYTHON'.
* m4/python.m4 (_AM_PYTHON_INTERPRETER_LIST): Add newer Python
versions, drop older ones. Also, sort the list with older versions at
the front, newer and generic versions towards the end. This makes the
algorithm pick the lowest version that meets the version requirement.
