* Added [overlaybd](https://containerd.github.io/overlaybd/) system extension to support accelerated container images.
The extension includes both [overlaybd](https://github.com/containerd/overlaybd/) as well as [accelerated-container-image](https://github.com/containerd/accelerated-container-image) tools.
Add `overlaybd` to [`/etc/flatcar/enabled-sysext.conf`](https://www.flatcar.org/docs/latest/provisioning/sysext/) to check it out.

There is no need to check the architecture twice. Also check for arm64
(MacOS) wherever we check for aarch64 (Linux).

From ee0e074c256ea1bcbcff2ed5a3e311becaf122cc Mon Sep 17 00:00:00 2001
From: James Le Cuirot <jlecuirot@microsoft.com>
Date: Mon, 28 Jul 2025 12:05:19 +0100
Subject: [PATCH 2/3] Respect aarch64 -march=|-mcpu= flag and check whether
-mcpu=native works
Packagers may specify a target system up front, which should be
respected. The CRC extensions are not strictly necessary as there is a
software fallback.
Otherwise, use -mcpu=native if it works (it won't when cross-compiling)
or -mcpu=generic+crc.
