The manual chapter on phony targets sez:
Since it knows that phony targets do not name actual files that
could be remade from other files, `make' skips the implicit rule
search for phony targets (*note Implicit Rules::). This is why
declaring a target phony is good for performance, even if you
are not worried about the actual file existing.
