[gpsd-dev] build failed minimal=on aivdm=on

[Jon Schlueter]

found that we have an unfulfilled dependency for nmea_ais_dump in gpsddecode with the minimal builds listed below

scons minimal=on leapfetch=off aivdm=on

scons minimal=on leapfetch=off reconfigure=on aivdm=on

scons minimal=on leapfetch=off aivdm=on ashtech=on

gcc -o gpsdecode -pthread gpsdecode.o -L. -lrt -lgpsd -lgps -lm 

gpsdecode.o: In function `decode':

gpsdecode.c:(.text+0x24d): undefined reference to `nmea_ais_dump'

collect2: error: ld returned 1 exit status

scons: *** [gpsdecode] Error 1

scons: building terminated because of errors.

These set of results was found using a build option matrix scan I put together here:
