static build fails to find plugins for application build

1. install B2Qt environment
2. build static Qt using it:

   ./configure -v -confirm-license -sysroot /home/kapinter/Qt/5.11.2/Boot2Qt/nitrogen6x/toolchain/sysroots/cortexa9hf-neon-poky-linux-gnueabi -prefix /work6/Qt/bin/Qt-imx6-static -opengl es2 -xplatform devices/linux-imx6-g++ -skip qt3d -skip qtandroidextras -skip qtcanvas3d -skip qtcharts -skip qtconnectivity -skip qtdatavis3d -skip qtgamepad -skip qtlocation -skip qtmacextras -skip qtnetworkauth -skip qtpurchasing -skip qtremoteobjects -skip qtscxml -skip qtsensors -skip qtspeech -skip qtwebchannel -skip qtwebengine -skip qtwebsockets -skip qtwebview -skip qtwinextras -skip qtxmlpatterns -nomake examples -nomake tests -commercial -static -qml-debug -alsa -v -device-option CROSS_COMPILE=/home/kapinter/Qt/5.11.2/Boot2Qt/nitrogen6x/toolchain/sysroots/x86_64-pokysdk-linux/usr/bin/arm-poky-linux-gnueabi/arm-poky-linux-gnueabi-
   

3. build qt example animatedtiles and linker gives errors:

Workaround is to add the missing plugins to the pro file with LIBS+=
