build: Implement --with-multilib-list for avr target
gcc
* config.gcc: For the AVR target, populate TM_MULTILIB_CONFIG.
* config/avr/genmultilib.awk: Add ability to filter generated multilib
list.
* config/avr/t-avr: Pass TM_MULTILIB_CONFIG to genmultilib.awk.
* configure.ac: Update help string for --with-multilib-list.
* configure: Regenerate.
