This change adds support of ARC ISAv2 processors in OpenWRT toolchain. In general gcc for ARC may compile code for both ISA versions simultaneously but libgcc will be built only for default architecture that's why it's necessary to specify --with-cpu on gcc configuration. As for uClibc we need to use different configurations for different ARC ISAs.
