[libstdc++, DOC] Update GNU gettext reference

[Gerald Pfeifer]

gettext has moved from sourceware.org (aka sources.redhat.com) a while
ago; this patch which I applied updates the documentation accordingly.

Note how it also adds a trailing slash to avoid a redirect and extra
round of communications between browser and web server.

I'll also ask overseers@ regarding the obsolete web page stub.
