The Python module pyyaml is required to build the docs, but it is only
listed in Documentation/sphinx/requirements.txt and is therefore missing
when Sphinx is installed as a package and not via pip/pypi.
Add pyyaml as an optional package for Debian- and Red Hat-based distros to
fix building the docs if you prefer to install Sphinx as a package.
