#### Testing the changes
- I tested the changes in this PR: **briefly**

#### Local build testing
- I built this PR locally for my native architecture: **x86_64**

* `site.tmac` changes from [Arch repo](https://gitlab.archlinux.org/archlinux/packaging/packages/groff/-/blob/main/site.tmac)
* `--with-doc` configure option removed upstream, builds/installs docs by default
* `${DESTDIR}/usr/lib` is empty, so no more `libgroff` - although can't find it mentioned in the changelog (which is [a whole novel](https://git.savannah.gnu.org/cgit/groff.git/tree/ChangeLog.123))

A patch file from https://github.com/void-linux/void-packages/pull/45300.patch is attached
