>Description:
SVRv4 code depends on System V IPC primitives, which might be loaded as
KLDs. If they're not loaded before svr4.ko, its loading procedure will fail.
>How-To-Repeat:
SystemV options needs to be disabled in your kernel configuration:
[..]
#options 	SYSVSHM			# SYSV-style shared memory
#options 	SYSVMSG			# SYSV-style message queues
#options 	SYSVSEM			# SYSV-style semaphores

# kldstat | grep sysv
# cd /usr/src/sys/modules/svr4
# make load
[..]
objcopy --strip-debug svr4.ko
/sbin/kldload -v /usr/src/sys/modules/svr4/svr4.ko
kldload: can't load /usr/src/sys/modules/svr4/svr4.ko: No such file or directory
*** Error code 1

Stop in /usr/src/sys/modules/svr4.
[..]

# dmesg | tail -1
link_elf: symbol msginfo undefined
