Hello Deval,

Sebastian is currently on vacation so he might need some time to answer.
I'll try to give some hints but I'm far from being as familiar with
libbsd as Sebastian is, so he (or some others) might have another opinion.

Regarding the header: Currently mainly the option headers are empty. If
you do a

   find -size 0 -name "*.h"

(or some other search for empty files) in the libbsd directory, the
empty headers are option headers and some machine dependent files.

So if you ask me, it should be OK to disable the mentioned
ofw_bus_subr.h especially because you disabled ofw in the whole file.

On the other hand an option header that you should add as an empty file
would be opt_platform.h in your patch 5/6.

Kind regards

Christian
