Add the library absence check as a kati stage check.

Primarily for use with build_test during presubmit.

Moved the check to main.mk to avoid nonobvious dependency on
product_target_FILES from main.mk to Makefile.

Test: m systemimage
Test: build/soong/build_test.bash
Test: m out/target/product/taimen/system/lib/libdexfile.so; m systemimage;
  check that "find"-based check fails
Test: Add a system library to APEX_MODULE_LIBS; m systemimage;
  check that "product_target_FILES"-based check fails;
  env DISABLE_APEX_LIBS_ABSENCE_CHECK=true m systemimage;
  check that it works

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For an outdated reference on Android.mk files, see build-system.html.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