I'd recommend you apply FreeBSD r210369 to the kernel instead.
When compat32 binary asks for the value of hw.machine_arch, report
the name of 32bit sibling architecture instead of the host one. Do
the same for hw.machine on amd64.
Add a safety belt debug.adaptive_machine_arch sysctl, to turn the
substitution off.
