Building `arm64e-apple-*` targets got linking warning,`found architecture 'arm64e.old', required architecture 'arm64e'`

[Wyvern]

Rust nightly, build with -Zbuild-std for all arm64e-apple-* targets.
got linking warning like below:

warning: linker stderr: ld: ignoring file '/Users/.../arm64e-apple-darwin/src/build/compiler_builtins/b8f06f1815e74221/deps/libcompiler_builtins-b8f06f1815e74221.rlib(lib.rmeta)': found architecture 'arm64e.old', required architecture 'arm64e'

I believe upstream LLVM only supports the old arm64e abi, while Apple's LLVM fork uses the new arm64e abi. Duplicate of #130085.

Yeah, the arm64e targets are fundamentally broken because Apple haven't upstreamed the necessary compiler support.

See the thread starting around #73628 (comment) for more info.
