Proof of concept for a multi-platform, native Gradle project

Gradle evolves more and more in the native application space. This project tries to evaluate its support for embedded platform development which aim different target architecture / embedded OS combinations in a common Gradle based framework.

The initial project consists of three simple components:

apps/blinky		The main application written in C
comps/timer		A simple timer driver mock-up written in C.
comps/gpio		A simple library that provides control of a GPIO port, written in C.

The goal of this proof of concept is to build different variants of the blinky application in one shot. The different variants differ by

buildTypes	_debug_ and _release_
flavors		_red_ and _green_

The mix of flavors and build types is set up in central *.gradle files at top-level project scope in:

project/gradle/
	buildtypes.gradle	
	flavors.gradle		
	platforms.gradle	
	repositories.gradle	
	toolchains.gradle

debug 
releae

green
red

x86 		Simualtion of the application on x86 based hardware (PC/Mac)
x86_64		Simualtion of the application on x86 based hardware (PC/Mac)
arm 		Bare metal ARM applicaiton (under development)
