Hah, I think I was onto something, but it's not what I thought:
%> objdump -p systray-qt5/systray-qt5 | fgrep PATH
RPATH /opt/local/libexec/qt5/lib
As a result, all 5.8.0 platform plugins give an error like this:
%> env LD_LIBRARY_PATH=/opt/local/testing/libexec/qt5/lib
QT_PLUGIN_PATH=/opt/local/testing/share/qt5/plugins
QT_QPA_PLATFORM_PLUGIN_PATH=/opt/local/testing/share/qt5/plugins/platforms
QT_DEBUG_PLUGINS=1 systray-qt5/systray-qt5
...

In /opt/local/testing/share/qt5/plugins/platforms/libqxcb.so:

and then finally the process fails with

This application failed to start because it could not find or load the Qt

IOW, I'll need to find a way to build that systray app in such a way that it
contains RUNPATH instead of RPATH.
Is that what qmake 5.8.0 should do with the patch from this codereview in
place?
R.
