When running under bazel, Emsdk should use the bazel python through something like py_binary instead of the system python

It seems like the bazel wrapper escapes the bazel sandbox and relies on having the correct version of python installed on the system. Is there a way to force it to use the bazel python tool chain?

Could you go into a bit more detail here? What sort of issues has this caused you? Referring to #1422, I am just using the native implementation of py_binary (not the one from rules_python) which I suspect still uses the system installed Python.

If I get time to work on #1422, I intend to switch it over to python_rules since that might work around bazelbuild/bazel#17629.

For example, https://github.com/emscripten-core/emsdk/blob/ce1d281ce65b5c7398b17ed6484efc6a3901df6f/bazel/emscripten_toolchain/emcc.sh
just invokes system python3.

Indeed it does, I am not sure what I was on about in my previous comment.
