target: zephyr: Select compile options by ARCH rather than BOARD (#1374)

Browse Source 
Currently we need to modify the JerryScript Makefiles for every new
board we want to work with. It is better to study the zephyr configuration
and used the CONFIG_ options to determine the right compiler flags.

We expose the CONFIG_ options to make by adding machinary to the makefiles
to import the Zephyr .config file, allow us to make the decisions we
need.
