`wasi-sdk-20` pre-release can be used to avoid building `wasi-libc` to enable threads. It's not possible to use `wasi-sdk-20` pre-release on Ubuntu 20.04 because of incompatibility with the glibc version: ```bash /opt/wasi-sdk/bin/clang: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.34' not found (required by /opt/wasi-sdk/bin/clang) ```
