PR target/51345
* config.gcc (tm_file target=avr]): Add avr/avr-multilib.h
(tmake_file target=avr): Add avr/t-multilib.
* config/avr/avr-c.c (avr_cpu_cpp_builtins): Use AVR_HAVE_8BIT_SP
to built-in define __AVR_HAVE_8BIT_SP__, __AVR_HAVE_16BIT_SP__.
* config/avr/genmultilib.awk: New file.
* config/avr/t-multilib: New auto-generated file.
* config/avr/multilib.h: New auto-generated file.
* config/avr/t-avr (AVR_MCUS): New variable.
(genopt.sh): Use it.
(s-mlib): Depend on t-multilib.
(t-multilib, multilib.h): New dependencies.
(s-avr-mlib): New rule to build t-multilib, multilib.h from AVR_MCUS.
(MULTILIB_OPTIONS): Remove.
(MULTILIB_MATCHES): Remove.
(MULTILIB_DIRNAMES): Remove.
(MULTILIB_EXCEPTIONS): Remove:
* config/avr/genopt.sh: Don't use hard coded file name;
pass AVR_MCUS from t-avr instead.
