+Note that Clang packages typically don't include cross-compiled builds of
+compiler-rt, libcxx, or libcxxabi, for `libclang_rt.builtins-wasm32.a`, libc++.a,
+or libc++abi.a, respectively, so they may not be usable without
+extra setup. This is one of the things [wasi-sdk] simplifies, as it includes
+cross-compiled builds of compiler-rt, libc++.a, and libc++abi.a.
