Describe the bug
The UFS S2S model does not compile with 2020.04-alpha1 due to missing files in the SRCS_F90 list in fv3gfs/makefile

To Reproduce
for example,
git clone https://github.com/ufs-community/ufs-s2s-model.git
cd ufs-s2s-model/FMS && git checkout 2020.04-alpha1
cd ../tests
./compile.sh $PWD../FV3 orion.intel 'CCPP=Y SUITES=FV3_GFS_2017_coupled,FV3_GFS_2017_satmedmf_coupled,FV3_GFS_v15p2_coupled MOM6=Y CICE6=Y CMEPS=Y' 1

Expected behavior
The model should compile without error
