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

https://github.com/Chocimier/void-packages-org waf3
https://github.com/void-linux/void-packages/pull/21227

Replace waf with waf3 where applicable
Intent is to remove waf build style.

Most of remaining packages use waf 1.6 that is incompatible with python3.
Ardour 6 will use newer waf.
lilv builds but installs some python modules that are to be checked for py3 compatibility.
flowcanvas is unmaintained and replacement is packaged, so will be removed, as well as already broken packages.
ladish won't use build style.

A patch file from https://github.com/void-linux/void-packages/pull/21227.patch is attached
