This is probably a question for the EOS repo (where wasm.cmake is define) since it appears they are using all the constituent toolchain parts independently, but from a brief glance at their wasm.cmake. But I'm guessing you need to set a WASM_ROOT environment variable that points to clang?

Closing this as obsolete, and because we are moving the code (see #698). If there is an issue with the build scripts, please file an issue against EMSDK
