FSF gcc-3.x for Atmel AVR cross-development

This brings the gcc compiler to the Atmel AVR 8-bit RISC family of
microcontrollers.

Included is the basic C++ compiler, although this is only of limited
use without a libstdc++, and it is little tested.

Supported debugging formats: -gstabs [default] and -gdwarf-2
Locally hack added: recognizes 0bXXX binary constants

Locally added support for the following AVR devices:

  ATtiny13/ATtiny2313             ATtiny25/ATtiny45/ATtiny85
  ATmega48/ATmega88/ATmega168     AT90PWM2/AT90PWM3
  ATmega164/ATmega324/ATmega644   ATmega165
  ATmega325/ATmega3250/ATmega645/ATmega6450
  ATmega329/ATmega3290/ATmega649/ATmega6490
  ATmega640/ATmega1280/ATmega1281
  AT90CAN128
