Wow, very nice. [This is how RPATH should always have been IMHO].

A libtool that doesn't need to relink anymore - that would be so awesome...

Thanks a lot - I knew there was a way to do this cleanly :)

Should we use $RUNPATH even independently from the -as-needed stuff?
I think it makes it much easier to have several versions of KDE around, if you
can really control which one is found at runtime (using LD_LIBRARY_PATH)
without the "hardcoded into the libs/bins" RPATHs taking precedence.
But well, since this fix makes it ok again to have -as-needed on by default,
it probably doesn't matter much what happens when disabling it.
