Subject: [PATCH] CMake/ELF: allow using Qt's full version number in the
 private tags

We added the feature to tag private symbols using the Qt major version
only, because us developers often move between versions and need to keep
compiled code working, even when using private API (we're supposed to
know what we're doing). Linux distributions, however, want to be told
that something used private API and therefore needs to be rebuilt. See
[1][2][3].

Distributors will learn about this feature when updating Qt causes the
existing patch to fail to apply.
