Fix GPS for n80xx devices

Why the hell does Samsung keep on derping the Makefile for GPS on
n80xx devices?  I'm getting tired of fixing this crap over and over
again.

Before they assumed wifi N80xx units didn't have GPS.  Now they're
keying compilation of the GPS stuff off of a nonexistent config
entry.

grr
