There is a new pull request by jnbr against master on the void-packages repository

https://github.com/jnbr/void-packages cc
https://github.com/void-linux/void-packages/pull/15968

I think the benefit of keeping it isn't worth the trouble it causes.

A patch file from https://github.com/void-linux/void-packages/pull/15968.patch is attached
