We already do this when building the modules as part of the kernel.
However, you can't eliminat ethe opt_*.h rules in the
sys/modules/*/Makefile because you still have to build in the building
in the world case.

If I understand it correctly, it is still inadequate. Many of the
opt_*.h rules in the makefiles have been elminated by having the
default rule for them.
