[gpsd-dev] [PATCH] Building test_libgps can fail with specifc build options.

[Robert Norris]

test_libgps will fail with this build command:
 scons shared=True socket_export=True minimal=True test_libgps
resulting with undefined reference to 'libgps_dump_state' errors

As test_libgps would force debugging on, yet libgps_dump_state() is compiled 
out.

Simply wrap libgps_dump_state() calls with suitable ifdefs
 and don't force the LIBGPS_DEBUG define in code.
