[meta-freescale] [meta-fsl-arm][RFC] qtbase: add xcb support for i.MX6

[Juha Vuolle]

Built fine on master. Can't say if it works as there is no example
apps or qmake to build my own (and I ended up applying the patch on
5.1.0 instead of the 5.0.2). But I did get out an image with the Qt
libs in place so I'll try tomorrow with my hand-built apps and cross
fingers for binary compatibility. The resulting libEGL.so.1 on the
sysroot/rootfs seems to be libEGL-wl.so i.e. wayland, is this OK?

On master-next there is some (maybe unrelated) error:
libEGL.so: undefined reference to `gcoOS_CreateDrawable'
when it is building
