In thinking about the order of operations, it occurred to me that
trying the last option first would make sense, so I did that (cleared
/usr/obj/usr/src/sys/GENERIC, then re-built and -installed the
kernel).

And the build machine came up in multi-user mode:

FreeBSD freebeast.catwhisker.org 12.0-CURRENT FreeBSD 12.0-CURRENT #404  r320884M/320891:1200038: Tue Jul 11 09:12:03 PDT 2017     root_at_freebeast.catwhisker.org:/common/S4/obj/usr/src/sys/GENERIC  amd64

I'll call that "success" and stop while I'm ahead. :-)

Thanks!

Peace,
david
