I think the problem might have started with some changes to the kernel
build infrastructure that result in reading make.conf and/or src.conf
when they didn't used to, so now KERNCONF with multiple entries is
defined differently in kern.post.mk than it used to be.
I wonder if this patch might fix it (I'm not in a position to test it
myself right now -- this is purely a shot in the dark)...
