Build system for Python stuff behaves strange

[blattms]

• After make clean copied stuff from the source tree (e.g. below tests) is missing and not copied again. Or at least I fail to find a way to do that.
• After make clean , make all does not seem to rebuild tests (at least for PYACTION I need to trigger the build manually).
• Changing e.g. PythonInterp.cpp and issuing make all does not rebuild the necessary objects.

Well, it could just be me being too stupid for the latter two points

@blattms is this still happening or is that resolved by now?
