Android-9 : Linaro_arm64 (Target - VM) - SwiftShader based software rendering for VM

[vinaykumarmp]

Android boot fails with Surfaceflinger errors .

Steps followed :

1. Modified external/swiftshader/Android.mk to build for arm64 - target. Able to build it successfully.

2. Modified : device/linaro/generic with below changes :

With qemu=1 from cmdline , android picks the swiftshader-gles path but Surfaceflinger breaks. (Also tried by avoiding drm_hwc & drm_gralloc during build but no help) .

Appreciate your inputs.
