4880. [bug] Named wasn't returning the target of a cross zone

Browse Source 
CNAME between to served zones when recursion was
                        desired and available (RD=1, RA=1). Don't return
                        the CNAME target otherwise to prevent accidental
                        cache poisoning. [RT #47078]
