Apple arm64e targets fail to link with newer Xcode 15

See tracking issue for these targets in #73628.
Building a project using the arm64e-apple-ios target fails to link when using Xcode 15.4. Using Xcode 14.3.1 works.
This might also be the case for arm64e-apple-darwin, but I can't test that due to rust-lang/cc-rs#1205.
$ cargo new foo && cd foo && cargo +nightly build --target=arm64e-apple-ios -Zbuild-std
// Or
$ ./x test --target=arm64e-apple-iosThe exact error is:

clang: error: linker command failed with exit code 1 (use -v to see invocation)
I feel fairly confident that we're passing the right arguments to the linker nowadays (this happens even with #129369), so I suspect it's the object files that we generate that's the problem somehow, but I may be mistaken?

Happens as far back as +nightly-2023-11-22, the day after the PR introducing these merged, so it's definitely due to changes in Xcode, not because of a regression in rustc.

The .old prefix in the warnings getting spammed would seem to hint that Apple has added a new identifier or ABI version for the arm64e target? This seems to indicate its an upstream LLVM limitation, perhaps.
Firefox has patched their LLVM build to set the correct arch flags based on Apple's LLVM output.
