re PR target/54607 ([avr]: Canadian cross build fails because gen-avr-mmcu-texi.c is compiled with the wrong compiler)
PR target/54607
* config.gcc (tm_file,avr): Add avr/avr-arch.h.
* config/avr/t-avr (gen-avr-mmcu-texi): Use CC_FOR_BUILD to
compile. Don't depend on TM_H. Use CFLAGS_FOR_BUILD.
* config/avr/avr.h (avr_arch, base_arch_s, mcu_type_s): Source out
to...
* config/avr/avr-arch.h: ...this new file.
* config/avr/gen-avr-mmcu-texi.c: Include avr-arch.h, stdio.h,
stdlib.h.
* comparator: Make letters smaller than digits.
* config/avr/avr-devices.c: Don't include headers if used in
gen-avr-mmcu-texi.c.
* doc/avr-mmcu.texi: Regenerate.
