Ok, as far as I understand it means nobody has successfully compiled Qt5 
+ webkit + xcb + mesa yet.
Perhaps, people use only the framebuffer with buildroot.

Unfortunately we have a dead-line for our project and my knowledge is 
too small to do it myself. I'm going for the third option, but with 
another company :-)

We're using a Freescale iMX6 MARS board, with the modular X.org server.
As drivers, I selected:

xf86-input-evdev
xf86-input-keyboard
xf86-input-mouse
xf86-input-tslib
xf86-video-fbdev

because I don't know which other video driver I should select for my 
platform...
