system.img for ranchu emulator

[Ye Roger]

I built a system.img using android-6.0.1_r22 to test ranchu emulator. I got the following error message. It seems gralloc is not built. Do you know why? what is the right tag that I should use to build a system.img for ranchu? I attached the error log file.

I fixed this issue after I changed the following files:

$ git status

It seems android-6.0.1_r22 is not ready to support ranchu. Is this a bug ? It seems nobody build AOSP images for ranchu, even though ranchu kernels are included in the latest SDK.
