doc: Makefile: add support for xelatex

Browse Source 
This patch makes the "latexpdf" target compile the documentation with
xelatex instead of the default pdflatex engine.

The reason behind this is stated in [YOCTO #14357]: pdflatex does not
support compiling foreign characters, so we need to resort to another
engine, here xelatex.

It also increases the texmf config buf_size to 10000000 to avoid a
compilation error.
