Log message:
        Make second expansion optional (partial implementation).
        
        I decided this feature was too impacting to make the permanent default
        behavior.  This set of changes makes the default behavior of make the
        old behavior (no second expansion).  If you want second expansion, you
        must define the .SECONDEXPANSION: special target before the first target
        that needs it.
        
        This set of changes ONLY fixes explicit and static pattern rules to work
        like this.  Implicit rules still have second expansion enabled all the
        time: I'll work on that next.
        
        Note that there is still a backward-incompatibility: now to get the old
        SysV behavior using $$@ etc. in the prerequisites list you need to set
        .SECONDEXPANSION: as well.
