QGroundControl cross-compilation

Is it possible to somehow compile QGroundControl for RK3399? I have this board (http://en.t-firefly.com/product/rocrk3399pc). I downloaded and installed friendlyCore (http://wiki.friendlyarm.com/wiki/index.php/How_to_Build,_Install_and_Setting_Qt_Application) to be able to compile for this chip. But at beginning of compilation I get error (Project ERROR: Unsuported Linux toolchain, only GCC 32- or 64-bit is supported). I found out that problem is at QGCCommon.pri file. It doesn’t contain if for friendlyCore compiler. Do anyone know how to get it working ? I tried few tutorials about compilation for raspberry pi, but they didn’t helped.

I will be grateful for any advise
