RFREND is defined in ap/plan9's sys9.h, but isn't in plan 9 as distributed

RFNAMEG will just have to do.

the symptom is that an APE program that uses select but also forks
and execs another program using select will end up with one side
or the other, or both, being confused when the rendezvous calls clash.
