Subject: [PATCH] Generates pstex/pstex_t from fig to accommodate xelatex

xelatex is note based on pdflatex (lualatex is) thus the \ifpdf macro
returns false.
As xelatex uses \ifpdf to identify the latex engine and thus will try to
insert ps files instead of pdf ones.

This patch adds make rules to also generate pstex and pstex_t files.
