RHEL 7.x and clone distros are shipped with Sphinx 1.1.x, with is incompatible with Kernel ReST markups. So, on those systems, the only alternative is to install it via a Python virtual environment. While seeking for "pip" on CentOS 7.3, I noticed that it is not really needed, as python-virtualenv has its version packaged there already. So, remove this from the list of requirements for all distributions. With regards to PDF, we need at least texlive-tabulary extension, but that is not shipped there (at least on CentOS). So, disable PDF packages as a whole. Please notice, however, that texlive + amsmath is needed for ReST to properly handle ReST ".. math::" tags. Yet, Sphinx fall back to display the LaTeX math expressions as-is, if such extension is not available. So, let's just disable all texlive packages as a whole.
