Revert it forward ;-).

Not sure about this. The current rule works, but requires more code
(first for the rule, then for .ORDER to make it work). Perhaps the
correct fix is to not rename y.tab.h. Renaming y.tab.c is another
mistake. It breaks breaks debugging (the renamed file contains line
numbers for the original). bsd.{prog,lib}.mk probably should override
sys.mk to do this better. It should also add the generated files to
CLEANFILES.
