I found the root cause, being that the multi-IP stack configuration on this platform is not being passed correctly through bash to the shell that make starts when running tests. When running the test under ksh, which has a deeper port, the test behaves correctly. As it turns out, this is a platform-specific issue with our bash port. This is not git's issue at all, nor the DNS resolver configuration (although I did find an independent problem there). Sorry to be a bother.
