It was mentioned at patch 0/9:
	https://www.mail-archive.com/linux-media@vger.kernel.org/msg101408.html

I opted to not change the HAVE_PDFLATEX, as the macro that sets the
latex variant on Sphinx latex Makefile is called "PDFLATEX". Also,
we might change it in the future to use some other tool or even add
some logic to allow supporting multiple tools, like we have with
DocBook.

The main goal of XeTeX is to add unicode font support to LaTex,
according to:
	https://en.wikipedia.org/wiki/XeTeX

We need that, as media uses a lot of math Unicode symbols inside
the documentation.
