building armv6 bootable media

hello,

after running 'make -C release NO_ROOT=yes release' for arm.armv6 i have
the following files:

% ls /src/obj/src/freebsd/src/minimal-deadlkres/arm.armv6/release/dist
METALOG			base.debug.meta		kernel/			kernel.premeta		tests.meta
base/			base.meta		kernel.meta		tests/			usr/

none of these appear to be bootable media, unlike arm64.aarch64,
riscv.riscv64, or amd64.amd64 which build memstick.img and disc1.iso:

% ls /src/obj/src/freebsd/src/minimal-deadlkres/arm64.aarch64/release
MANIFEST		bootonly-memstick/	disc1-disc1/		disc1.meta		kernel.txz.meta		mini-memstick.img.meta	src.txz.meta
base-dbg.txz		bootonly-memstick.meta	disc1-disc1.meta	dist/			lib32-dbg.txz		packagesystem		tests.txz
base.txz		bootonly.iso		disc1-memstick/		ftp/			lib32.txz		packagesystem.meta
bootonly/		bootonly.iso.meta	disc1-memstick.meta	ftp.meta		memstick.img		release
bootonly-bootonly/	bootonly.meta		disc1.iso		kernel-dbg.txz		memstick.img.meta	release-done.meta
bootonly-bootonly.meta	disc1/			disc1.iso.meta		kernel.txz		mini-memstick.img	src.txz

do i need to do something special to build bootable media for armv6?

this is with main 793745fad866.
