    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.
