Gribmap in GrADS 2: index file not portable to other endianess

  In GrADS v1 the index file created by gribmap used to endianess-portable.
The same index file could be used on both little and big-endian machines
alike. I just tried the *.idx file created on my Mac PPC with "a2" and it
does not work on Linux. If I rerun gribmap on Linux it produces a different
idx file, and now GrADS v2 can read my Grib-2 file just fine.

  Being able to use the same idx on different machine is very important for
people distributing data on DVDs.
