Wrong executable published to rubygems for arm64-darwin on > v3.20

[DerekStride]

What version of protobuf and what language are you using?
Version: > v3.20
Language: Ruby

What operating system (Linux, Windows, ...) and version?

MacOS 12.3.1

What runtime / compiler are you using (e.g., python version or gcc version)

arm64

What did you do?

Steps to reproduce the behavior:

Download either one of the following gems from arm64-darwin:

3.20.1.rc.1 - April 06, 2022 arm64-darwin (274 KB)
3.20.0 - April 01, 2022 arm64-darwin (274 KB)

See all here: https://rubygems.org/gems/google-protobuf/versions

Check the Mach-O Header and it's for x86 architecture (small script to parse the headers: gist://derekstride/mach-o.rb)

What did you expect to see

An executable from arm64 architecture.

What did you see instead?

An executable from x86 architecture.

Error from stacktrace:

Has this ever worked? I see there is an open bug for it here: #8682

This may have been broken by: #9566. If that's the case, then reverting would break Ruby 3.1 binaries on other platforms.

Unless there is a quick fix for this, we may have to just disable the arm64 build on macOS for 3.20.1. arm64 users would need to build from a source gem.

I don't think so, All existing gems published with pre-built packages for arm64-darwin were broken when I created the issue. If you have access you may want to yank them from RubyGems so projects running on arm64-darwin can build from source as a fallback.

After they are removed from rubygems I think this issue can be closed and #8682 can remain open.

I've yanked the arm64-darwin gems. Closing in favor of #8682.
