This defines the spec always when the core has it, not only
override it when it differs from the core's value.

AVR: Always define __AVR_PM_BASE_ADDRESS__ in specs provided the core 
has it.

gcc/
	* config/avr/gen-avr-mmcu-specs.cc (print_mcu) <*cpp_mcu>: Spec always
	defines __AVR_PM_BASE_ADDRESS__ if the core has it.
