envsetup.sh: Update text in lunch menu for clarity

Updates the lunch menu text to make it clearer that the choices in lunch
menu are not fully comprehensive. As the list comes from common lunch
choices the text now refers to 'common combinations' and informs that
you can 'specify your own'. This should help developers who are unsure
why they cannot find their desired lunch target in the list.

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For an outdated reference on Android.mk files, see build-system.html.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