The details are a bit hazy in my memory after so many months, but it was
something like this: either because of the way we split, for example,
qtbase into different ports, or because of the additional targets we
build in ports like x11-toolkits/qt5-gui, we do end up with a situation
where end up with a broken linker invocation.

  # e.g. qt5-gui
  c++ -o libs/libQt5Foo.so file1.o ... fileN.o -lQt5FooDependency ... \
      -L/usr/local/lib -L/build/dir/libs

so the installed and older libQt5FooDependency.so is picked up instead
of the newly-built one.
