Any further working on this patch, or if any help is still needed? I'm very excited to have neovim 0.6.1 in guix! I did some research on source code of lua package. From https://github.com/guix-mirror/guix/blob/f9c62b23cc88541756656b3ec602ce987828d906/gnu/packages/lua.scm#L179 we can find that luajit deleted "powerpc64le-linux" from the supported system list, which lua package didn't. So I think we should keep that fallback.
