[Buildroot] Can't run Weston. Gtk 3.14, Wayland 1.6

[Andrey Rodionov]

Hello,

My device on ARM9 CPU, has only touchscreen, no keyboard. I try to use on
it GTK3 and Wayland as backend, compiled with Buildroot2014.11.


Start Weston:
openvt -c 2 -s -- weston --backend=/usr/lib/weston/fbdev-backend.so
--tty=2  --log=/tmp/weston.log


weston.log:
Date: 1970-01-01 UTC
