There's no feasible way to find every instance in every zone file of a 
CNAME pointing to a particular name, just as there's no feasible way to 
find every instance of the phrase "rubber buggy bumpers" scrawled into 
every personal diary throughout the world.

If you want to find all CNAMEs pointing to a particular name in 
*your*own* zones, then you could grep the zone files. Or to find all 
instances in zones for which you have zone transfer permission, do the 
zone transfers of each and look through the data.
