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

https://github.com/tornaria/void-packages python3-pkgconfig
https://github.com/void-linux/void-packages/pull/35371

python3-pkgconfig: add depends to pkg-config
Seems natural, since AFAICT python3-pkgconfig cannot be used without pkg-config.

Not worth the revbump IMO.

A patch file from https://github.com/void-linux/void-packages/pull/35371.patch is attached
