rules.mak: Do not hardcode path for "echo" It is basically the only tool with full path here and I don't see any reason for it. We don't use special echo options that would fail on the shell built-in echo. Also don't hardcode path for losetup. sudo should make sure you have the relevant location in your path, and that the path is sanitized, otherwise your sudo setup is broken.
