Prefer arch-dependent over arch-independent pages if the name priority,
the section number, and all names match. Changes little on installed
systems except the ordering of apropos(1) results, because we install
base and Xenocara manuals in different trees, but fixes lookup of pages
like apm(4) vs. apm(4/amd64) in man.cgi(8).
Issue discovered by martian67 on freenode and reported via tj@.
