Restore/redirect https://review.coreboot.org/p/seabios.git so older versions still work
I tried building coreboot 4.7 and it failed because that url went 404.
Make a rule in apache or nginx to rewrite/redirect so older builds still work.
I checked in menuconfig, there is no option to point to an alternate url,
of course I could dive into the source, but if I had root on the server,
fixing the webserver would be about as fast a fix and a fix for everyone.
