Before make parses that .if line, it has already decided which 
.OBJDIR to use.  Yes, you can change it later, and I even said 
so in an earlier draft of my message, but then decided to delete 
it as irrelevant to my point, and because I didn't feel like a 
digression into why that also has problems.
