[wwwdocs] Broken links

[Philippe Baril Lecavalier <pbl dot ltx at gmail dot com>]

Enclosed is a patch modifying three broken links, on three separate
pages. I also added some indications to about.html on how to submit a
patch for the web site for those who do not have commit access, which is
precisely what I have been instructed to do (so now it becomes
documented).

See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=59184> for more
information.

All the best,

Philippe Baril Lecavalier
