[Buildroot] [PATCH] gpsd: fix Python-related build failure

[spdawson at gmail.com <spdawson@gmail.com>]

From: Simon Dawson <spdawson@gmail.com>

The gpsd build falls over on certain autobuild machines; an example follows.

  http://autobuild.buildroot.net/results/42b435c271b0d791365e18ad974c7eecca8896a0/build-end.log

ImportError: No module named simplejson:
  File "/scratch/peko/build/gpsd-3.7/SConstruct", line 1072:
    from leapsecond import save_leapseconds
  File "/scratch/peko/build/gpsd-3.7/leapsecond.py", line 27:
    import gps.misc
  File "/scratch/peko/build/gpsd-3.7/gps/__init__.py", line 9:
    from gps import *
  File "/scratch/peko/build/gpsd-3.7/gps/gps.py", line 17:
    from client import *
  File "/scratch/peko/build/gpsd-3.7/gps/client.py", line 9:
    import simplejson as json                        # For Python 2.4 and 2.5
make: *** [/scratch/peko/build/gpsd-3.7/.stamp_built] Error 2

The problem appears to be the indiscriminate importing done in the module
initialisation for the gps Python module. If the simplejson module is not
available for the host Python, then the build fails.

For the purposes of the build, the simplejson import is superfluous; in fact,
since SConstruct pulls in gps.misc via leapsecond.py, all of the imports in
the gps module initialisation are superfluous.
