Colin Cross 42669e6dc7 Allow Soong to export multiple proguard flags files
Soong uses lists of proguard flags files from dependencies instead
of a single concatenated file.  Allow Soong to pass the list to
make, which will concatenate it.

Move the check inside ifdef LOCAL_SOONG_RESOURCE_EXPORT_PACKAGE
in case Soong exports an Android library with an empty
LOCAL_SOONG_EXPORT_PROGUARD_FLAGS.

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For an outdated reference on Android.mk files, see build-system.html.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