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.
