Further to this, we'd previously discussed the danger of the wrong
libtexinfo library being loaded if a "libtexinfo" library
was installed elsewhere (see below).
In my report, I had LD_LIBRARY_PATH set which was causing the issue, but
in any case, locating and loading "libtexinfo.so" in texi2any directly
would eliminate any risk of either not finding the file, or finding the
wrong file.
