Subject: [PATCH] Replace `which` with `command -v`

Some distributions such as Arch Linux no longer install `which` by
default through the base package (see
https://www.archlinux.org/news/base-group-replaced-by-mandatory-base-package-manual-intervention-required/).

The maintainers have explained why `command -v` is superior:
