reduced link interface: some link breakage possible

Hi,
I just committed a patch which enables the reduced link interface for shared
libraries unconditionally for all libs created using KDE4_ADD_LIBRARY().
So if you suddenly get some undefined symbols when linking, this may very well
be the reason.
What to do then ?
1.) Don't panic !
2.) You are probably using symbols from some library which you don't link to
directly, but which was dragged in via one of the other libraries you link
to, and these "dragged in" libraries have now been mostly removed.
In this case, add these missing libraries explicitely to the
TARGET_LINK_LIBRARIES() command.
(because: less dependencies for packages, faster startup, some advantages in
keeping binary compatiblity).
3.) If that doesn't help, ask on kde-core-devel or kde-buildsystem.
I know it's late in the release cycle, but it wasn't possible earlier, and we
can't wait any longer with this, so we have to go through this now.
Hope that not too much breaks,
Alex
