[PATCH 3/8] Makefile: Add check of font package availability

Subject: [PATCH 3/8] Makefile: Add check of font package availability

Add existence check of relatively recent font packages required for
experimental targets.

Those targets used to just print info on required font, and to run
"pdflatex".  Now "make" aborts with a message indicating where to
see if any of required font packages is missing.
