Comment:
Drafting until [version 3.2.0](https://github.com/mindstorm38/portablemc/pull/115) is released, it contains some improvements that make it trivial to start the game under `x86_64-musl` & `aarch64-musl` systems which I could test as well which I'll document the relevant pieces about in `README.voidlinux`.
