Enforces bitness match of ARC compilers and linkers invoked building LLEXT apps by inheriting -mcpu flag from Zephyr. The ARC toolchain becomes confused without the -mcpu flag. On qemu_hs5x we see GCC select elf32-littlearc64 for linking an object previously compiled as elf64-littlearc64. Fixes #80949 Signed-off-by: Lauren Murphy <lauren.murphy@intel.com>
