[bazel] [rules_foreign_cc] ModuleNotFoundError: No module named 'tools'

When building a simple hello world binary with Meson, I am hitting the following error
```
mesonbuild.utils.universal.EnvironmentException: Unknown compiler(s): [['/home/developer/.cache/bazel/_bazel_developer/25e07d78077dfe1eca932359d50e41ef/sandbox/processwrapper-sandbox/9/execroot/_main/external/emsdk/emscripten_toolchain/emcc.sh']]
```
Digging a bit deeper, it seems `emcc.py --version` is failing and unable to find the tools module.

```

Perhaps this isn't included in the `compiler_files` filegroup which is passed to the toolchain?
