--- Comment #13 from boger at us dot ibm.com --- Then my question is: why isn't this "fallback" code always built for GO and available to run instead of waiting until it hits this situation and then built and run? In the situation you are describing it sounds like it is related to whether or not there is a static libnss available which could be determined at GO build time.
