Description:
Directs output of texi2html to log files (GOP 9) for translated docs.
There is a slight gotcha with this change, that if there is an error in
running texi2html, then the dev has to know to look at the relevant log
file.  However, it's highly unlikely this will ever occur - we leave
--error-limit for texi2html at its default value of 1000, so it's almost
impossible to cause it to fail.  The huge benefit of this change is
further reduced output from make doc, and the ability to get a list of
all the errors in the docs in a logfile. These could be sent to the
relevant author/translator.
