Isaac Chen c311ff6b68 Update GF board variable for dynamic partition 
Goldfish specific board variable:

BOARD_EMULATOR_DYNAMIC_PARTITIONS_SIZE

is used to create misc_info.txt, which is needed to mix GSI or CSI on
Goldfish vendor image, and need to reflect the size of the current
super.img, which is now set to 4G+8M (from 3G+8M previously).

Bug: 174442566
Test: $ lunch aosp_x86_arm-userdebug; m
      $ ls -l $OUT/super.img	# make sure it's 4 GB
      $ grep -i dynamic_partitions_group_size $OUT/misc_info.txt
      super_emulator_dynamic_partitions_group_size=4294967296

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For an outdated reference on Android.mk files, see build-system.html.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