Description
I'm trying to use clang-9 to compile and use wasi-sysroot, but additionally the libclang_rt.builtins-wasm32.a file is required to link into the final wasm module. It is not obvious how to build this file without building the llvm/clang submodules first, so it would be much appreciated if you can add relevant instructions. Thanks a lot!

Research direction
Start by tracing how clang-9, wasi-sysroot, and the llvm/clang submodules are used to produce libclang_rt.builtins-wasm32.a. Add relevant build instructions to the appropriate wasi-sdk documentation, including whether the submodules must be built, and confirm that a newcomer can follow them to obtain the archive for final wasm linking.
