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:
Traceback (most recent call last):
