Log Message:
Change qmake to not add the target directory as rpath.
This would leak rpath references to the build directory and
libtool should take care of this already. Non-libtool builds
might be broken by this, but they shouldn't use -Wl,-R either,
but -Wl,-rpath. Bump revision of qt3-libs (rpath changes) and
qt3-tools (qmake changes).
