[Ncep.list.nems.announce] Upcoming NEMS commit: NUOPC linker option bug fix needed for FV3

[Samuel Trahan - NOAA Affiliate]

NEMS developers,

Wednesday at noon eastern time, we're committing a bug fix to the
NEMS/src/conf/configure.nems.NUOPC.  This is urgently needed for the FV3
GFS work.  The previous configuration used the ESMF-specified version of
the compiler libraries for linking, which did not match the ones used when
compiling.  This new version uses the application-specified compiler
libraries for both compiling and linking.  (Those are the ones set via
modulefiles.)

Regression tests pass for NEMSGSM, NMMBTestBed and WAM-IPE (bitwise
identical results).

The change is trivially simple:
