Gaël PORTAY Feb. 12, 2018, 4:25 a.m.
The mesa's EGL/eglplatform.h header includes X11 headers unless the flag
MESA_EGL_NO_X11_HEADERS is defined[1].

A build issue happens when mesa3d is selected as then OpenGL EGL backend
but the XCB library is not selected.

This commit tells qmake to pass the cflag MESA_EGL_NO_X11_HEADERS to
make and prevent from including the missing X headers.

The issue QTBUG-66233 is opened in the Qt tracker[1].

Fixes:
