    Explicitly terminate some make rules · 490bec02

    Generic rules like:
    
      %: %.in
    
    have the downside that the source (%.in) itself matches the target
    (via %.in: %.in.in). This leads to things like:
    
      Looking for a rule with intermediate file `doc/examples/hooks/ipsec.in.in'.
       Trying pattern rule with stem `ipsec.in.in'.
       Trying implicit prerequisite `doc/examples/hooks/ipsec.in.in.in'.
       Trying pattern rule with stem `ipsec.in.in'.
       Trying implicit prerequisite `doc/examples/hooks/ipsec.in.in.in'.
       Looking for a rule with intermediate file `doc/examples/hooks/ipsec.in.in.in'.
      Rejecting impossible implicit prerequisite `doc/examples/hooks/ipsec.in.in'.
    
    To fix this, we need to tell make that such rules are terminating, so
    that it doesn't recurse into them.
