Two way sync seems somewhat dangerous. Perhaps b2 aborting with an error if 
it sees a newer file in boost/ will be enough.

On second thought, this won't work when the same header is present in more 
than one module. This happens when a header is being moved and is added to 
its new module before being removed from its old place. Currently b2 doesn't 
mind, it just updates the link twice and the later copy wins.
