This patch simplifies the integration with the zephyr build system whilst at the same time enriching the set of build targets to allow zephyr to be configured using its kbuild features. It works by exploiting "make outputexports", a feature of the zephyr build system that makes the zephyr compiler configuration available to other build systems in an easily accessible manner. Whilst looking at the build we also correct the implementation of clean so that it no longer destroys any custom zephyr configuration. Like any other zephyr application one must use "make pristine" to remove the config too. JerryScript-DCO-1.0-Signed-off-by: Daniel Thompson daniel.thompson@linaro.org
