If it is to not be an option, then it should be deprecated as an option
and all of that removed. FWIW, I tested NetBSD-current without this
option and it compiles cleanly (not that I used it). Seems like someone
needs to make a decision one way or the other about COMPAT_43 and FreeBSD.

I was going for a small kernel config, hoping that it'd be quick to
build, not take up lots of space, etc, so only put in what I thought
was necessary.
