Remove.  This has been moved to avr-gcc to become the standard version
of AVR-GCC now.

Fix the COMMENT to tell this is GCC 4.x rather than 3.x.  Pointed out
by Simon Barner.

Revert the default debugging format to stabs but offer DWARF-2 as an
option (rather than being the default).  AVR-GDB currently understands
stabs much better than DWARF-2.

Fix a bug in patch-zz-atmega256x that caused -fcall-prologues to
generate faulty code.  This affected libgcc.a as it uses this option.
This bug has been originally found and fixed by Wang Guohui but I
missed his fix when adding the patch here.

Rename ATmega164/324 to ATmega164P/324P, add support for ATmega644P,
ATmega165P, and ATmega169P.

Add the patch mentioned in GCC bug report:

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=26504

to support DWARF-2 generation, and enable the respective configuration
option.
