Control: severity -1 important

Vincent: Thanks for discovering the issue with a statically compiled
binary loading a dynamic library.

Lowering the severity again.

Of course this will help! The tests are not just run at build time.
The tests are also regularily run against zsh "as installed" via

You're both right — depending which busybox-built package you've
isntalled: "busybox" or "busybox-static".
