The GPL only prevents you from distributing the GPL'd library
without distributing the application source code.
You can distribute the application object code
without the application source code without violating the GPL
and let users link it into the GPL'd library themselves.
I don't think that there is any practical way for the FSF
or the library developers to prevent users from doing this.
