It comes from the htmlxref.cnf file. (It may be installed under
/usr/share/texinfo/.) The link produced above matches the
current entry for the "gcc" manual in that file.
Changing that file would change the link, e.g.
--- a/util/htmlxref.cnf
+++ b/util/htmlxref.cnf

However, it's wrong to make it link to a specific version.
The gcc developers need to provide a stable, version-independent link
for the manual. This link would have worked in the past, but I don't
know how recently it broke.
I'm attempting to CC the gcc mailing list stated on their documentation page
to see if anyone there can give any information.
