hobart_intel doesn't build if you have compiler/nag module loaded

[mnlevy1981]

I load the compiler/nag module every time I log on to hobart (via my .bashrc file). If I run the following:

$ cd $CESMDIR/cime/scripts
$ ./create_newcase -compset [doesn't matter] -res [doesn't matter] -mach hobart -compiler intel -case CASEDIR
$ cd CASEDIR
$ ./case_setup
$ ./case_build

I get an error in the PIO build about having trouble with the MPI and netCDF libraries. However, a well-placed module purge:

$ cd $CESMDIR/cime/scripts
$ ./create_newcase -compset [doesn't matter] -res [doesn't matter] -mach hobart -compiler intel -case CASEDIR2
$ cd CASEDIR2
$ ./case_setup
$ module purge
$ ./case_build

builds successfully. I haven't dug into scripts to try to track this down, so I don't have a fix to suggest. This appears to be the case in both cime4.5.10 (cesm1_5_beta06) and cime4.5.16 (latest tag to date) -- I've tentatively added this to the cesm2 milestone, thinking it would be good to see if the problem still exists after the python refactor (I assume the Machines files will all look different?) before trying too hard to find a solution.

Fixed in cime5 (verified).
