Subject: [PATCH] feat(build): check that we copied all binaries
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Sometmmes a new binary is added to an output, like in the `dhall-yaml`
case, where yaml-to-dhall was added.

This uses `lr` because I can’t be bothered to figure out how to use
`find` to the same effect.
