Fix .env_mach_specific.sh when unsetting env #4558

Closed jgfouca closed 9 months ago

jgfouca commented 9 months ago

When an env var value is None, this tells CIME to unset the environment. This use case was not being handled in the creation of .env_mach_specific.sh.

Test suite: by-hand Test baseline: Test namelist changes: Test status: [bit for bit, roundoff, climate changing]

Fixes [CIME Github issue #]

User interface changes?:

Update gh-pages html (Y/N)?:

Test fail is due to a cdash network issue, merging.
