ip2k
This is an Ubicom cpu, and they maintain a GNU port in house. There are references to it on their web site, though I didn't see a convenient link to download it. Probably not much worth to the FSF version of this port if they aren't contributing patches to it.
ns32k
Everytime we have tried to get rid of ns32k, some NetBSD users have complained. There is still a maintained NetBSD port for this.

There are probably only about a dozen working machines left in existence, though. Not really worth our trouble if they aren't interested in maintaining the gcc port themselves.
