This error message is pretty useless in quiet mode. To get a more
verbose error message, you can try building with 'make -j2 V=1'.

The general problem is that TeX is a huge group of packages, and you
might be missing one small package that contains a specific style or
font that GNU Texinfo uses.

Fortunately for you, Dan Sebald recently had a similar error, and maybe
the fix that he found also works for you:

Yes, because the 'all' target builds the octave program, but it also
builds documentation, configuration files, and icons. If building the
documentation fails, the 'all' target fails, but the octave program has
been built.
