reinoud a233fbd53e Fix major bug in make(1) ... due to shadowing of the dotLast path used for
the .DOTLAST primitive by a boolean variable with the same name, this whole
mechanism was broken ... it doesn't save much stat calls but it was wrong.

Thanks to Jason Thorpe for the other shadow-variable fixing patches he
made.
