No, but it apparently happens if you build kernel modules separately, or
via ports.  Or if you build kernel modules for head from older branches.

Obviously that would be better, but I received several private messages
from people that were annoyed that I "broke" their kernel module builds,
and expected me to fix it.  There was also at least one such posting on
freebsd-current@, where somebody's nvidia-driver port fell over due to
my change.

I did think about adding a fatal error message to each of the kern.mk
files that includes bsd.own.mk, but you can't really do a full sanity
check until you add some sort of version number to the bsd.*.mk files.
