Disable objc_msgSend stubs in clang. Fixes #16223. #16231
Conversation
Clang will by default emit objc_msgSend stubs in Xcode 14, which ld from earlier Xcodes doesn't understand. We disable this by passing -fno-objc-msgsend-selector-stubs to clang.

Applies the same fix as dotnet/macios#16231. We recently started seeing the same issue in our runtime builds, see dotnet#89925. This is because the AzDO build machines use Xcode 14 but the Helix machines are still using Xcode 13 so linking an Xcode-14-built static library fails. Fixes dotnet#89925

This is because the AzDO build machines use Xcode 14 now but the Helix machines are still using Xcode 13 so linking an Xcode-14-built static library fails. This happens in e.g. libSystem.Native.a or libSystem.Globalization.Native.a (the two libraries where we're using Objective-C). Fixes #89925
