link from www.gnu.org -> gcc.gnu.org

[Mumit Khan]

Looking at http://www.gnu.org/software/gcc/ , there is no obvious link
to gcc.gnu.org. I hope this discontinuity is fixed soon, since all
the real useful info is on gcc.gnu.org (such as the FAQ, build info
and so on). This link should prominently be featured in the News
section.

The other nit is the pointer to vger.rutgers.edu as the snapshot
location, obviously a holdover from gcc-2.x days.
