FYI for aarch64/armv7 lib32: armv7 kyua test sys/net/if_bridge_test:gif with preloaded if_bridge.ko still panics in my style of testing

I finally got around to testing lib32 some more, first
trying the panic case that I'd gotten in early testing.
The below is without any special lib32 patching for
testing, just my normal non-debug environment updated
to a lib32-present aarch64 FreeBSD vintage.

Reminder: /usr/obj/DESTDIRs/main-CA7-chroot/ contains an
armv7 installworld distrib-dirs distribution DB_FROM_SRC=1
result. (It also has various ports installed.)
