        * config/avr/t-avr:
        (HAVE_DOUBLE_MULTILIB, HAVE_LONG_DOUBLE_MULTILIB): Remove vars.
        (HAVE_DOUBLE32, HAVE_LONG_DOUBLE32, WITH_LONG_DOUBLE)
        (HAVE_DOUBLE64, HAVE_LONG_DOUBLE64, WITH_DOUBLE): Set from
        tm_defines and pass to genmultilib.awk.
        * config/avr/genmultilib.awk: Use these variables to add double32
        and / or long-double32 multilib(s) as needed.
