Shame that make can't be smarter about when it needs to recompile modules, on
its own.  It seems like it would be easy to parse a .c file and see if a new -D
define affected the resulting .o file, or keep around a table of what options
were used to compile each .o file.  Anyways, not worth worrying about...
