 meta-acer: added patched A500 Android 3.1.10 kernel

 * kernel 3.1.10 recipe and corresponding defconfig
 * The chroot script only mounts /dev, /proc and /sys, and chroots to /dev/mmcblk1p2
 * The chroot image is a simple initrd image, nothing fancy.
 * The kernel cmdline is specified with CONFIG_CMDLINE in the recipe
