"pure" Qt packages using QMake build system have QT_INSTALL_PLUGINS
and QT_INSTALL_LIBS set to multiarch paths [1].
In the best case, only binNMU is needed. In the worst, *.install files
need to be updated.
The list of "affected packages" isn't based on reverse dependencie as
we usually do for library transition with binary incompatibility, but
on the usage of these variables by the build system. We have also some
packages using CMake like kde4libs that relies on the same variables.
hope it answers the question.
