Makefile: detect when PYTHON_PATH changes

Browse source 
When make is run, the python scripts are created from *.py files that
are changed to use the python given by PYTHON_PATH. And PYTHON_PATH
is set by default to /usr/bin/python on Linux.

However, next time make is run with a different value in PYTHON_PATH,
we failed to regenerate these scripts.
