There is an updated pull request by andry-dev against master on the void-packages repository

https://github.com/andry-dev/void-packages libluv
https://github.com/void-linux/void-packages/pull/13648

New package: libluv-1.30.1
This PR adds libluv (a Lua wrapper for libuv).
The reasoning for having this is to prepare for Neovim 0.4: it requires this library to build properly.

A patch file from https://github.com/void-linux/void-packages/pull/13648.patch is attached
