A temporary fix to allow the satingest changes to be implemented on August 29 without causing GSI to crash. Issue with the CRTM means that GSI will crash unless NOAA-21 radiances are switched off.

Obsproc version numbers should remain unchanged unless the obsproc changes are implemented before or at the same time as the satingest changes.

Update release notes to mention compilation error fix for gfs_bufr code. Resolves NCO bugzilla #1208.

For some reason the sorc/build_tropcy_NEMS.sh no longer works on WCOSS2 machines.   @RussTreadon-NOAA and @aerorahul found fixes that allow the build to complete.  This PR implements one of these fixes - removing the references to the NEMSIOGFS module, which is being loaded but does not have a version number attached.

Six executables result from this build as expected.   They should still be tested for functionality.

This references #1812.
