probably you/we'll have to make it for a correct qmakespec, one that targets Qt5.7 (and g++6 core libs, just in case); besides, you seem to have a bleeding-edge misalignment on most fundamental x11/xcb libs anyway. may i ask why you're stepping up so fast?
meanwhile i'm still on Qt5.6 (LTS) though already on g++6, where all qstuff builds and runs fine as it ever was :)
