* add metaware toolchain support in build system:
* compiler
* linker
* binutils
* gcc objcopy is used because it can't be replaced
with mwdt's binutils currently
* To use ARC metaware toolchain, you'd better:
* in Linux/Unix environment
* install arc gcc/zephyr toolchain to use gnu's objcopy
tool
* set ZEPHYR_TOOLCHAIN_VARIANT=arcmwdt
