FirebaseAnalytics build error with -ld_classic, -ObjC and iOS 17.6 on Xcode 26 Beta

### Description

FirebaseAnalytics fails to build when using -ld_classic, -ObjC and setting Minimum Deployment to iOS 17.6 or older on Xcode 26.0 beta 7 (17A5305k)

I've created a sample project where I just added the Firebase Analytics Package using SPM and the two linker flags https://github.com/tiagomartinho/firebase_analytics_ld_classic_issue

### Reproducing the issue

1. Add FirebaseAnalytics
2. Add -ld_classic and -ObjC in OTHER_LDFLAGS in the build settings
3. Set the Minimum Deployment to iOS 17.6 or older
4. Build the project
