["Philippe Mathieu-Daudé" <philmd@linaro.org>]

From: Akihiko Odaki <akihiko.odaki@daynix.com>

macOS versions older than 12.0 are no longer supported.

docs/about/build-platforms.rst says:
> Support for the previous major version will be dropped 2 years after
> the new major version is released or when the vendor itself drops
> support, whichever comes first.

macOS 12.0 was released 2021:
