Aarch64 patches for uefi-next.git

Hi Steven,

Please find attached two patches used for aarch64 work. Each patch goes into a different topic branch in the end, not in the linaro-topic-fvp branch as we discussed earlier. Still, they are quite simple, so shouldn't cause much of a problem.

0001-tools_def-AARCH64-use-CROSS_COMPILE-variable.patch

The above patch goes into linaro-topic-misc.

0002-FVP-Add-support-for-EDK2_USE_ANDROID_CONFIG-build-pa.patch

The above patch goes into linaro-topic-fvp.

Please let me know if these cause you any problems, but it would be good to get them into uefi.git for the -rc4 and the -03 release respin.

You can also pull both patches/branches from my tree:

Thanks, Ryan.
