Hermes won't build on M1 Mac

[Saadnajmi]

Environment

1. react-native -v
2. npm ls react-native-macos:
3. node -v: v12.21.0
4. npm -v: 6.14.11
5. yarn --version: 1.22.10
6. xcodebuild -version: Xcode 12.4 Build version 12D4e

Issue

If you try to build RNTester-macOS on an M1 Mac with hermes enabled, it fails. You have to keep hermes disabled in the pod file to build RNTester-macOS on an M1 Mac.

Steps To Reproduce

1. Clone the react-native-macos repo (https://github.com/microsoft/react-native-macos)
2. Setup RNTester & open Xcode project (yarn && cd RNTester && pod install && open RNTesterPods.xcworkspace)
3. Try to build RNTester-macOS for Target "My Mac" (in my case it's am M1 Mac mini)

The Expected Behavior

It builds successfully

Actual Behavior

Several Errors:

Looks like this will be fixed by facebook/hermes#475 =)

@kelset A little bird told me you maybe knew of a workaround for this? If so, share it here.

But based on the previous comment it seems like this fixed with a newer version of Hermes, so this will be naturally resolved. @Saadnajmi does that work for you?

@chrisglein yeah, that's fine! It's not an actual issue for me I just wanted to make sure it was tracked. Looks like Hermes is directly tracking so we can close this.
