You should have sysroot location pointed at /opt/poky/1.1.1/sysroots/arm*-poky-linux/.

In terminal, you should do the followings to cross compile. Forgetting $CONFIGURE_FLAGS would bring you into native build, not cross build.
1. source source /opt/poky/1.1.1/environment-setup-x86_64-poky-linux
2. sh autogen.sh $CONFIGURE_FLAGS
3. make;
