My notes are about building armv7 (32-bit) ports into packages,
not aarch64 ports into packages (not 64-bit).

All Apple's arm implementations do not support armv7 code as I
understand. qemu based emulation would be required in order to
build armv7 packages form ports in that context.

But things would largely be the same for building aarch64 ports
into packages. RPi5/RPi4B's or analogous small arm boards from
others may be more common overall. (I just happen to have access
to RPi*'s instead of other alternative small arm boards. So I
used what I've got.)

My notes are intended to be suggestive about effective
poudriere-devel based pacakge building use for folks using such
small arm boards, at least those with 4 cores and 2 GiBytes+
RAM. On systems with more cores or 32 GiBytes of RAM, I do
various things differently.
