man arch reports:
MACHINE MACHINE_CPUARCH MACHINE_ARCH
arm64 aarch64 aarch64
. . .
arm arm armv6, armv7
So I'd not expect arm64 in MACHINE_ARCH . But
sys/modules/Makefile has (from a grep for MACHINE_ARCH):
.if ${MACHINE_ARCH} =3D=3D "amd64" || ${MACHINE_ARCH} =3D=3D "arm64"
.if ${MACHINE_ARCH} =3D=3D "amd64" || ${MACHINE_ARCH} =3D=3D "arm64" || =
${MACHINE_ARCH:Mpowerpc64*}
Another issue may be that COMPAT_FREEBSD32_ENABLED is only
put to use in the Makefile for MACHINE_CPUARCH being i386
or amd64 :
.if ${MACHINE_CPUARCH} =3D=3D "i386" || ${MACHINE_CPUARCH} =3D=3D =
"amd64"
_agp=3D agp
.if ${MACHINE_CPUARCH} =3D=3D "i386" || !empty(COMPAT_FREEBSD32_ENABLED)
. . .
=3D=3D=3D
