On amd64 main-n251456-22c4ab6cb015-dirty (Dec.-7): /boot/kernel/ng_ubt.ko is getting "symbol sysctl___net_bluetooth undefined"

Back when I upgraded the ThreadRipper 1950X amd64 system to (line split for readability):

# uname -apKU
FreeBSD CA72_16Gp_ZFS 14.0-CURRENT FreeBSD 14.0-CURRENT #25 main-n251456-22c4ab6cb015-dirty:
Tue Dec  7 19:38:53 PST 2021    
root@CA72_16Gp_ZFS:/usr/obj/BUILDs/main-CA72-nodbg-clang/usr/main-src/arm64.aarch64/sys/GENERIC-NODBG-CA72 
arm64 aarch64 1400043 1400043

I started getting notices like:

Dec  7 18:38:57 amd64_ZFS kernel: link_elf_obj: symbol sysctl___net_bluetooth undefined
Dec  7 18:38:57 amd64_ZFS kernel: linker_load_file: /boot/kernel/ng_ubt.ko - unsupported file type

(Not that I use the bluetooth on the system.)

Is this expected for a kernel of that vintage?

sysctl___net_bluetooth seems to be from one or more of:
