"Float80 is not available on target platform" when building for macOS on Apple Silicon

[insidegui]

I get this error building for macOS on Apple Silicon using 12.5 beta 3 (12E5244e):

'Float80' is unavailable: Float80 is not available on target platform.

I suspect that has something to do with Apple Silicon so the check should be different based on architecture.

This is when importing UserDefault BTW :)
