    Default AVR to DWARF2 debug
    
    This switches the AVR port to generate DWARF2 debugging info by
    default since the support for STABS is going to be deprecated for
    GCC 12.

            * config/avr/elf.h (PREFERRED_DEBUGGING_TYPE): Remove
            override, pick up DWARF2_DEBUG define from elfos.h
