Subject: [PATCH] Improve doc for web pages; reproducible tarballs

* admin/make-tarball.txt: Make the tarballs more reproducible.
Fix instructions for web pages as best I can (they are still
incomplete).
* make-dist (default_gzip): Add --no-name for gzip.
(taropt): Add options to make the build more reproducible.

+FIXME: The above instructions are not quite complete, as they do not

 Browsing <https://web.cvs.savannah.gnu.org/viewvc/?root=emacs> is one
 way to check for any files that still need updating.
