Fix for missing RPATH

[David Faure]

KDE_RPATH contains the kde+qt+x directories but not the "prefix of this module".
When I compile kdepim head into its own prefix, readelf shows that RPATH points to 
kdelibs-prefix before kdepim-prefix, every time a binary links to a kdelibs library before
a kdepim library. Of course it can be fixed by fixing the order of the link line in every
Makefile.am ... but a less fragile solution would be to do this at the right place IMHO.
