I have backported the patch[1] pointed by Peter Seiderer and the build
of qt5multimedia, qt5wayland and qt5webkit passed successfully on next
branch where the workaround is not preset (+ qt5.10).

As you can see, the -DMESA_EGL_NO_X11_HEADERS flag is passed to the
compiler.

So sorry for the noise; I finally found the time (copy a simple patch
and start a build). I can send a patch serie today for master that
reverts my workaround.

Note: It is not tested on other EGL platform without XCB and MESA3D/EGL
with XCB.
