From a3a510958e5bb012c89d6e9759ac3312faf174eb Mon Sep 17 00:00:00 2001

Subject: Remove logic to use the current installed Python as default. Always
 prefer the default version and fallback to the first entry of
 PYTHON_VERSIONS_ACCEPTED, which is supported by the current system. Also
 honour PYTHON_VERSIONS_ACCEPTED and _INCOMPATIBLE, when PYTHON_VERSION_REQD
 is used.
