[3.9] bpo-41100: Support macOS 11 and Apple Silicon (GH-22855) (GH-23295)
* [3.9] bpo-41100: Support macOS 11 and Apple Silicon (GH-22855)
Co-authored-by: Lawrence D’Anna <lawrence_danna@apple.com>
* Add support for macOS 11 and Apple Silicon (aka arm64)
As a side effect of this work use the system copy of libffi on macOS, and remove the vendored copy
* Support building on recent versions of macOS while deploying to older versions
This allows building installers on macOS 11 while still supporting macOS 10.9..
(cherry picked from commit 41761933c1)
Co-authored-by: Ronald Oussoren <ronaldoussoren@mac.com>
* Back port of changes to _decimal to support arm64
* temp_dir is in test.support in 3.9
