gcode_process.c: more preprocessor conditions for homing movements. 

Well, optimizer isn't _that_ smart. It apparently removes
empty functions in the same compilation unit ( = source code file),
but not ones across units.

This saves 10 bytes binary size per endstop not used, so 30 bytes
in a standard configuration. All without any drawbacks.
