Comment (by chrisj):

 If the RSB is the same git hash used to build the installed tools then a
 verify operation should work. The RSB should build exactly the same tools
 if nothing has changed. This is a fundamental requirement of the RSB. If
 the RSB git hash has changed the only 100% certain way for the RSB to know
 if the changes effect your built tools is to build them. The RSB source
 and configuration could have changed, the user's environment or the host
 may have changed. Each of these factors could effect the build.

 Maybe a hash of the user's environment, a hash of all source used and a
 hash of the internally built doit script might be a way to determine if
 the result is the same. The only concern is something being missed and the
 tools should have been built.

 Once 4.11 is released and the tools become stable and the update cycle
 slows down. For release branches we could look at ways to compare builds
 of the tools and to see what changes and make that information available
 so users can see if they need to update.
