So I'd not expect arm64 in MACHINE_ARCH . But<br>
sys/modules/Makefile has (from a grep for MACHINE_ARCH):<br>

Another issue may be that COMPAT_FREEBSD32_ENABLED is only<br>
put to use in the Makefile for MACHINE_CPUARCH being i386<br>
or amd64 :<br>
<br>
.if ${MACHINE_CPUARCH} == "i386" || ${MACHINE_CPUARCH} == "amd64"<br>
