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.

Add support for detecting and installing missing packages
on Mageia. I opted to use "urpmi" at the install instructions,
as this is present on Mageia since ever. Yet, if I were using
Mageia 6, I would likely be using "dnf", as it is, IMHO,
easier to use.
Tested with Mageia 6.

ImageMagick actually uses librsvg for conversions when converiting
from SVG (actually, it uses rsvg-convert). That causes the build to
fail with:
WARNING: Error #1 when calling: /usr/bin/convert /home/mchehab/docs/Documentation/media/uapi/v4l/selection.svg /home/mchehab/docs/Documentation/output/latex/selection.pdf
convert: delegate failed `'rsvg-convert' -o '%o' '%i'' @ error/delegate.c/InvokeDelegate/1919.
convert: unable to open file `/tmp/magick-8883oOQfHzrA5trM': No such file or directory @ error/constitute.c/ReadImage/544.
Add the corresponding dependencies.

On newer versions of graphviz packaging on Fedora, it is needed to

Instead of using 3 commands to install a virtualenv, use
a single one, reading the requirements from this file:

Solving Sphinx dependencies can be painful. Add a script to
check if everything is ok.
Tested on:
- Fedora 25 and 26;
- Ubuntu 17.04;
- OpenSuse Tumbleweed;
- Arch Linux;
- Gentoo.
