mtools: ensure install-info isn't used

mtools calls install-info at 'make install' time if available after
installing the mtools info page - But as we don't use the info pages for
anything / remove in target-finalize, this is a waste of time and a
potential cause of build failures as reported on the list:

So ensure configure doesn't find it.
