The patch builds on my fedora 31 machine and the document octave.pdf
looks okay. Pictures are all fine.

The Fedora buildbots are now fine too. Except for gcc-fedora. But
that's a problem that was there already before. texi2dvi fails. Looks
like a specific texlive package is missing. However from the error log,
it is difficult to tell which package is missing. Hmm.
