##########
# This makefile builds local unit tests that run locally on the development machine.  Note
# that it may be necessary to install some libraries on the dev maching to make the tests
# build.
#
# The same unit tests are also built by Android.mk to run on the target device.  The tests
# should always build and pass in both places.  The on-device test is what really matters,
# of course, but debugging is often somewhat easier on the dev platform.
