Log message:
        Minor objdir rework to extend flexibility.
        
        the first shot of objdir implementation implied that you did:
        
        cd cluster
        ./configure --objdir... etc.
        cd /path/to/objdir
        make
        
        now you can:
        
        mkdir objdir
        cd objdir
        /path/to/configure
        make
        
        NOTE: in this case you don't need to specify objdir. it will be 
automatically
        set up for you.
        
        As a nice side effect you can also be anywhere on the fs and do:
        
        /path/to/configure --objdir=/path/to/obj
        cd /path/to/obj
        make
        
        and it will work.
