Bug#183860: On the GPL/GFDL conflict in texinfo.tex

[Nathanael Nerode <neroden@twcny.rr.com>]

Any file which builds with texinfo.tex missing or empty is OK as far as 
this license conflict goes.  (The GFDL is still a non-free license, of 
course, and I'm sad that sarge will deliberately contain lots of 
non-free stuff, but that's another matter.)

I think this case actually includes all the .info and .html files; if 
I'm not mistaken, makeinfo ignores texinfo.tex completely, so makeinfo 
--info, makeinfo --html, makeinfo --xml, and makeinfo --docbook are all 
OK.  I could be wrong of course. :-/

Sadly any .dvi, .pdf, or other file generated using TeX is an illegal 
license combination and is undistributable.

Safer just to remove all that non-free GFDL stuff.
