Right, I'm not sure whether it is necessary to have this, but it was a
bit of configuration information that was not available at the
interpreted level of the language.

Right, I wasn't sure what to do.  We have both words_big_endian and
words_little_endian in C++, so I just put both in octave_config_info.
If neither are true, I imagine it is a bug.  Would it be better to
have a different single value stored in octave_config_info?  If so,
what would you like to call it?
