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.
