New submission from Florin Spătar <florinspa...@gmail.com>:
On HP-UX, python can no longer find extension modules with the '.sl' suffix.

This works fine in python 3.8.5

It seems to be related to recent changes from https://bugs.python.org/issue42604
Given the file name is _m2crypto.sl, python 3.8.11 can no longer find it. Based
on https://www.python.org/dev/peps/pep-3149/#pep-384, my understanding is that
python should search for the following file names when extension module
_m2crypto is imported (in this order):
_m2crypto.cpython-38.sl
_m2crypto.so
Python can only load the extension module if the file name is
_m2crypto.cpython-38.sl
