BTW, this is a pre-existing problem not the fault of this patch,
but while we're fooling with the behavior of python lookup would
be a great time to fix it: we should add something like

AC_ARG_VAR([PYTHON], [path to Python executable])

Aside from improving the "configure --help" documentation, this
will prevent insane results from using inapplicable cached
conclusions about what Python we've got. Since more and more
people seem to be using configure cache files, I think we need
to be more careful about declaring relevant variables.
