hosts_access requires a couple of externs to be provided by
the caller.  Hence, the test fails.  I've cc'ed this to the
ITS system and will commit a fix for this soon.   I think
we should just check for 'main' in -lwrap... (which I thought
we actually did do at one time, obviously it was incorrectly
changed).
