System images of aosp_$arch are used as GSIs in P, and traditional GSI
users often need a special vbmeta image to disable verity (if AVB is
employed) befrre they flash the GSI.
"BOARD_BUILD_DISABLED_VBMETAIMAGE := true" builds such vbmeta.img
Bug: 79393905
Test: # For arch in arm, arm64, x86, x86_64, do
$ lunch aosp_$arch; m -j # found vbmeta.img under $OUT

Android Make Build System
This is the Makefile-based portion of the Android Build System.
For documentation on how to run a build, see Usage.txt
For a list of behavioral changes useful for Android.mk writers see Changes.md
For an outdated reference on Android.mk files, see build-system.html. Our Android.mk files look similar, but are entirely different from the Android.mk files used by the NDK build system. When searching for documentation elsewhere, ensure that it is for the platform build system -- most are not.
This Makefile-based system is in the process of being replaced with Soong, a new build system written in Go. During the transition, all of these makefiles are read by Kati, and generate a ninja file instead of being executed directly. That's combined with a ninja file read by Soong so that the build graph of the two systems can be combined and run as one.
