As requested by Jon, change the version check, in order to not

say:
./scripts/sphinx-pre-install

Note: It is recommended at least Sphinx version 2.4.4 if you need PDF support.
Detected OS: Fedora release 31 (Thirty One).
To upgrade Sphinx, use:
/devel/v4l/docs/sphinx_1.7.9/bin/python3 -m venv sphinx_2.4.4
. sphinx_2.4.4/bin/activate
pip install -r ./Documentation/sphinx/requirements.txt
If you want to exit the virtualenv, you can use:
deactivate
All optional dependencies are met.
Needed package dependencies are met.
If Sphinx is not detected at all, it
