Would you prepare libclang_rt.builtins-wasm32.a for wasm32-wasi-threads? In the wasi-sdk-24.0-x86_64-linux/lib/clang/18/lib, only wasi, wasip1, and wasip2 exist.

I manually linked libclang_rt.builtins-wasm32.a from wasip1, which resolved the issue, but I encountered:

(import "env" "__floatunditf" (func $fimport$2 (param i32 i64)))
(import "env" "__floatditf" (func $fimport$3 (param i32 i64)))

It seems that clang is unable to link libclang_rt.builtins-wasm32.a.
