and then run:
```sh
-make WASM_CC=/path/to/clang/with/wasm/support \
- WASM_AR=/path/to/llvm-ar \
- WASM_NM=/path/to/llvm-nm
+make CC=/path/to/clang/with/wasm/support \
+ AR=/path/to/llvm-ar \
+ NM=/path/to/llvm-nm
```
This makes a directory called "sysroot", by default. See the top of the Makefile
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.
