In Xcode 14 / ld 819, we are running into the following errors when linking against certain objective-c archive libraries:
```
ld64.lld: error: libUberTest_objc.a(UBDeallocObserver.o):(symbol +[UBRandomObserver observeRandomOn:callback:]+0x84): relocation BRANCH26 is out of range: 135504028 is not in [-134217728, 134217727]; references _objc_msgSend$copy
```

```
All the symbols are in our objc code, we are able to mitigate this by disabling objc selector stubs with `-fno-objc-msgsend-selector-stubs` applied to all clang calls.
