LRPS2 core for Apple Silicon?

Start by reproducing the reported make failure in the repository and inspect the build configuration and 3rd-party/rapidyaml dependency path referenced by common/StringUtil.h. Then trace how the core is built for the Apple x86_64 and arm64 targets. Done means the core builds for Apple Silicon and is available from the arm64 nightly download path.

I was hoping that LRPS2 could be built for Apple Silicon? For whatever reason, it's Intel only:

https://buildbot.libretro.com/nightly/apple/osx/x86_64/latest/

https://buildbot.libretro.com/nightly/apple/osx/arm64/latest/

I needed to open RetroArch with Rosetta to even see the core as an option to download:

Is there some sort of technical reason why it's x86_64 only? I tried building the source code myself but it failed/errored out

Any help would be awesome 😀 👍🏻
