And here 2/2 with the device -> arch mapping for gas.
Ok for trunk? Johann * config/avr/avr.h (device_to_arch): Rename to device_to_ld. (avr_device_to_arch): Rename to avr_device_to_ld. (avr_device_to_as): New prototype. (EXTRA_SPEC_FUNCTIONS): Add device_to_as. (ASM_SPEC): Use device_to_as to get -mmcu= and -mno-skip-bug=. * config/avr/driver-avr.c (avr_device_to_as): New. (avr_device_to_arch): Rename to avr_device_to_ld.
