Canceling Implicit Rules
------------------------

   You can override a built-in implicit rule (or one you have defined
yourself) by defining a new pattern rule with the same target and
dependencies, but different commands.  When the new rule is defined, the
built-in one is replaced.  The new rule's position in the sequence of
implicit rules is determined by where you write the new rule.

   You can cancel a built-in implicit rule by defining a pattern rule
with the same target and dependencies, but no commands.  For example,
the following would cancel the rule that runs the assembler:

     %.o : %.s
