	Commit files forgotten in r242966.

	* config/avr/avr-arch.h (avr_mcu_t) [flash_size]: New member.
	* config/avr/avr-devices.c (avr_mcu_types): Add flash size info.
	* config/avr/gen-avr-mmcu-specs.c (print_mcu): Remove hard-coded
	prefix check to find wrap-around value, instead use MCU flash size.
	For 8k flash devices, update link_pmem_wrap spec string to
	add --pmem-wrap-around=8k.
	* config/avr/specs.h (LINK_RELAX_SPEC): Move link_pmem_wrap from
	here...
	(LINK_SPEC): ...to here.
