Issue Description:

Hi Apple,

I've been re-syncing my swift repo and found I couldn't build a toolchain with beta 6 or beta 3 (as it suggests in the project README) giving an error building part of lldb saying _main undefined for architecture arm64. I've just successfully completed a build using beta 2 (the last beta before Apple Silicon). Should the README be updated or is there a specific reason why beta 3 is listed as the preferred version?

@johnno1962 I had the same issue moving from beta 1 to beta 6, to build successfully you have to pass the --swift-darwin-supported-archs 'x86_64' flag on the build-script.
Perhaps this should have to be be in the docs somewhere
