Mark argument as unused
The `loc` argument may or may not be used, depending on some #ifdefs. Mark it as ATTRIBUTE_UNUSED, though it might be worth polishing the whole target hook to not depend on the #ifdef'ed code at all. gcc/ChangeLog: * common/config/avr/avr-common.c (avr_handle_option): Mark argument as ATTRIBUTE_UNUSED.
