Cant compile crate-type cdylib on macOS

[codenutt]

I'm trying to build a project with a crate-type of lib, staticlib, cdylib on macOS. The project is blank, just importing and referencing ring. If I remove cdylib, it works fine.

System
macOS Ventura 13.4, M1
rustc 1.71.1 (eb26296b5 2023-08-03)

Main error:

ld: in /Users/codenutt/code/t/target/debug/deps/libring-08f7f88fe5c951d4.rlib(aesv8-armx-ios64.o), building for macOS, but linking in object file built for iOS Simulator, file '/Users/codenutt/code/t/target/debug/deps/libring-08f7f88fe5c951d4.rlib' for architecture arm64

I think you'd be more likely to find somebody to help you with this if you posted a link to a GitHub Repo that allows somebody to git clone and cargo build to reproduce this.

FWIW this seems to be fixed by rust-lang/cc-rs#848.

Thanks for reporting back!
