avoid wasting OS flag bits. In the future we'll probably use fileassoc to achieve this (once there is a way to make fileassoc persistent) or in the shorter term libelf, so that we can add and remove the note on demand instead of burning bits on each binary. Of course since this is a tool, this means that we'll need to think about how to handle libelf...
