[meta-freescale] eglinitialize() failed using "gpu-viv-bin-mx6q-sfp‏" libs

[kongling]

Hi,

    I have worked it out.

    weston-launch in systemd is launched as user "app", which have no permission to read and write "/dev/galcore" (crw------).
    I add a service in systemd to change the permission of "/dev/galcore".
    +ExecStartPre=-/bin/sh -l -c "chmod a+r /dev/galcore"
    +ExecStartPre=-/bin/sh -l -c "chmod a+w /dev/galcore"

    After rebooting, weston-launch is runing successfully by "systemd --user", weston-simpel-egl could be launched in the wayland terminal.

BR,

konglingxin

Supplement：
    I checked the systemd-coredump file, and got these messages:
