OK, I see that since texinfo 4.9, released June 29, 2007, texi2dvi
(and texi2pdf, since that is just a wrapper for texi2dvi --pdf) have
an option for specifying the build directory.  Since that has been
available for more than 5 years, I think it is reasonable to use it.

I checked in the following change.

Does it work for you?
