Since there are no dependencies, the command only gets run
if there is no file named driver. And remember that in un*x, a
directory is a file! Hence no reason to run the rule.

Solution: Read the node "Phony Targets" in the GNU make manual,
and add

.PHONY: driver

to your Makefile. Then make will always pretend that no file named
driver exists.
