The only solution is to duplicate what libtool does, which is to determine 
how to run a program linked against uninstalled libraries.

Options are:
1) setting the proper environment variable when possible 
(DYLIB_LIBRARY_PATH, LD_LIBRARY_PATH, etc.)

2) relinking the program if no other suitable method is found

Note that a standard Linux uses option #2, because LD_LIBRARY_PATH won't 
work on a standard KDE installation that used --rpath.

Also note that the fact that we run program we've just built makes it 
impossible to do a KDE cross-compilation. The clean solution for this 
would be to split all programs we need for building KDE from the KDE 
build itself.
