Isaac Chen e44b0d96b9 Set proper CPU variant for aosp_arm 
System image of aosp_arm products is the new GSI in Pi.
Its arch variants need to be the same as the legacy GSI built
with aosp_arm_ab so it can pass related CTS/VTS tests.

Bug: 80401108
Test: $ lunch aosp_arm-userdebug; m -j; emulator # booted OK
      $ lunch aosp_arm-userdebug; m -j cts

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For an outdated reference on Android.mk files, see build-system.html.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.
