The busybox package is not available on macOS.
getoptions runs checks on installation that (by default) require
busybox. The busybox specific checks are now only run on other
platforms.
checkInputs used to be added to nativeBuildInputs. Now we have
nativeCheckInputs to do that instead. Doing this treewide change allows
to keep hashes identical to before the introduction of
nativeCheckInputs.
