The thing is that if you solve the problem of rebuilding, then the issue of 
the name of the ELF version is moot.

For a Linux distribution, whose most frequent updates are a full patch or 
minor release, the changes in the private API are significant and require 
rebuilding everything.

For Qt's own developers, the updates are very minute and most often don't 
break the private API.
