Subject: [PATCH] libselinux: Use Python distutils to install SELinux python
bindings
SWIG-4.0 changed its behavior so that it uses: from . import _selinux which
looks for _selinux module in the same directory as where __init__.py is -
$(PYLIBDIR)/site-packages/selinux. But _selinux module is installed into
$(PYLIBDIR)/site-packages/ since a9604c30a5e2f ("libselinux: Change the location
of _selinux.so").
In order to prevent such breakage in future use Python's distutils instead of
building and installing python bindings manually in Makefile.
Follow officially documented way how to build C extension modules using
distutils - https://docs.python.org/3.8/extending/building.html#building
Fixes:
- selinux python module fails to load when it's built using SWIG-4.0:
>>> import selinux
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib64/python3.7/site-packages/selinux/__init__.py", line 13, in <module>
from . import _selinux
ImportError: cannot import name '_selinux' from 'selinux' (/usr/lib64/python3.7/site-packages/selinux/__init__.py)
>>>
SWIG-4.0 changed (again?) its behavior so that it uses: from . import _selinux
which looks for _selinux module in the same directory as where __init__.py is -
$(PYLIBDIR)/site-packages/selinux. But _selinux module is installed into
$(PYLIBDIR)/site-packages/ since a9604c30a5e2f ("libselinux: Change the location
of _selinux.so").

...
It's related to the following Python change
https://docs.python.org/dev/whatsnew/3.8.html#debug-build-uses-the-same-abi-as-release-build
Python distutils adds correct link options automatically.
- selinux python module doesn't provide any Python metadata
When selinux python module was built manually, it didn't provide any metadata.
distutils takes care about that so that selinux Python module is visible for
pip:
$ pip3 list | grep selinux
selinux 2.9
