ARC processors are highly configurable, so ARC toolchain supports big amount of mcpu options for all that HW configurations. As difference in many configurations among the same processor family usually doesn't affect Zephyr code we don't want to create Kconfig option for each possible CPU configuration (just to map Kconfig option to correspondent mcpu value in 'cmake/gcc-m-cpu.cmake'). Instead we prefer being able to set proper mcpu value individually for any ARC SoC and using 'cmake/gcc-m-cpu.cmake' just for reasonable defaults. To apply SoC-related changes for build-options on early stages of building 'tune_build_ops.cmake' should be created in appropriate SoC directory.
