Jesse Wattenbarger 765487390f Fallback on PYTHON path in Makefile
- Change default PYTHON in Makefile to be ranked choice
- Fix `PYTHON_VERSION` target that expects just a word
- Use native GNU Make `$(subst ,,)` instead of `sed`
- Add 'version-for-buildyml' target to simplify ci

If I understand correctly, this change should make
'$(PYTHON)' work how we want it to everywhere. Before
this change, on develpers' machines that don't have
a 'python3.9' in their path, make would fail. With this
change, we will prefer python3.9 if it's available, but
we'll take python3 otherwise.
