python: PYTHON_LIBS is not set in Python 3.8 (RHBZ#1705482).

Browse Source 
Python 3.8 no longer links C extensions to -lpython, instead relying
on the fact that the python binary itself already contains those
symbols.  This means $PYTHON_LIBS is empty and so the Python bindings
are not built.

Use a different test to see if the python module is available.
