There's a closed pull request on the void-packages repository

proot: update to 5.2.0.
https://github.com/void-linux/void-packages/pull/33272

Description:
- Delete obsolete patches and fix the rest.
- Add pkg-config (otherwise, undefined talloc_* refs abound).
- Use docs/GNUMakefile to generate manpage.

I could still use some help getting this to cross-compile on ARM architectures; whenever I try it, I get `pkg-config: No such file or directory`. It could be the case that I'm simply using `pkg-config` wrong (my C isn't great, to be honest).
