 That's not what I mean.
 It may be detected automatically, but need to digging history to find
 how to fix.

 buildlink3.mk should not be used for the purpose.
 If it used for resolve PYTHON_VERSIONS_ACCEPTED,
 it will be hard to do recursive revision bump from shlib version bump.
 And it will not work as expected if pyversion.mk is not included before
 any of py-*/buildlink3.mk.
