--- Comment #6 from Bjoern A. Zeeb <bz at FreeBSD.org> ---
(a) it should be WITHOUT_VIMAGE as that is the current default and you need
other places as well to properly add much an option.

(b) it's a kernel config file option and not a build/make option; to my very
best knowledge all user space changes were designed to be able to dynamically
cope with VIMAGE (and really only libkvm comes to my mind currently)

(c) and make.conf to me seems the entirely wrong granularity for this.

(d) lastly see SRCS.* in HEAD and sys/conf/kern.opts.mk which is getting a lot
closer to what you are looking for (along with a kernel build tree) though
those seem to be driven from src.conf, which I hadn't realised;  we should find
people who understand what the design had in mind.  I would love to have these
things derived from a kernel config file really but I am staying out of that
make foo.
