I had a similar issue on a different project. Installing LLVM from brew and making sure brew's LLVM was called (by updating PATH) instead of using Xcode's worked for me.

~ % clang --version       
Apple clang version 15.0.0 (clang-1500.3.9.4)
Target: arm64-apple-darwin23.5.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

versus:

~ % export PATH=/opt/homebrew/Cellar/llvm/18.1.6/bin/:$PATH                             
~ % clang --version

I have encountered exact same error when compiling surrealdb

I've encountered the same issue building psm on Apple mac m4, OSx 15.2

to reproduce:

git clone https://github.com/rust-lang/stacker/

add crate-type to Cargo.toml

wasm-pack build

I tried to debug as much as I could. The issue occurs linking libpsm-6197a72eaab962c7.rlib:
