[yocto] [meta-yocto][PATCH] enable aarch64 support for qemu in yocto

[Kai Kang]

Enable aarch64 support for qemu in yocto. Var QEMU_TARGETS in poky.conf
overrides the var in qemu recipe, so add in poky.conf too.

Use linaro prebuilt aarch64 for test. Test steps:
1 run native qemu with aarch64 image:

$ wget http://people.linaro.org/~alex.bennee/images/aarch64-linux-3.15rc2-buildroot.img

$ tmp/sysroots/x86_64-linux/usr/bin/qemu-system-aarch64 -machine virt -cpu cortex-a57 -machine type=virt -nographic -smp 1 -m 2048  -kernel aarch64-linux-3.15rc2-buildroot.img


2 run qemu-system-aarch64 on core-image-sato of qemux86-64
$ runqemu qemux86 qemuparams="-m 2048"

When booted, run
$ qemu-system-aarch64 -machine virt -cpu cortex-a57 -machine type=virt -nographic -smp 1 -m 2048  -kernel aarch64-linux-3.15rc2-buildroot.img

Boot could boot aarch64 image successfully.
