I know this is required for at least one feature, because TestSectionAPI.py has
failures if zlib isn't enabled. So I think it's useful for users to be able to
check.
Now that it's in the config, I have also used it to make a test annotation so
we don't get the failure in TestSectionAPI.py when zlib is disabled.
Which for future reference was:
