Cleanup Issue-URLs in Code · Issue #63902 · dotnet/runtime identified a workaround in place and it seems the backing issue has been resolved but the workaround remains.

• The original issue was: Bad IBC data causing official build failures · Issue #33303 · dotnet/runtime
• The PR that applied the workaround was: Disable IBC on OSX by jkoritzinsky · Pull Request #43839 · dotnet/runtime

The workaround should be evaluated to determine if it's still necessary. With the findings, we should either update the code to remove the workaround, or the code comment to reference an open issue for tracking when we can remove the workaround.
