Subject: Update PYTHON variable

`which python3` will likely show the latest version of python installed on system, so, it should go the first.
I think, it's not necessary to write all of possible versions of python. You can just use `which python3 || which python`...

Subject: Check PYTHON is properly defined

We don't need to check for all the various versions, that's just a
maintenance burden because `python33` shouldn't ever be available if
`python3` isn't.

Added a check for whether `PYTHON` is empty or just whitespace because
that's useless and could actually lead to problems, if `setup.py`
happens to be on the `PATH`.
