build.7: Improve make delete-old example
Be more explicit that deleting old files and libraries needs to be
really after you're rebooted a third time and you're really actually
sure your applications aren't using old libs, following irc discussion.
Also adjust an example slightly to fit on 80 character console.
MFC after: 3 days
Discussed with: emaste, fuz, jhb
