GCC 4.x, and caused the compilation to fail due to the -Werror option
used.
Remove an annoying assembler warning in the ATmega256x patch that was
frequently triggered by large C switch() statements in GCC, and
generally considered to be a regression. The author of that patch
agreed that the warning isn't particularly useful anyway for a number
of reasons, and recommended to just drop it.
Also fixed is the way the tweak for amd64 -> x86_64 is done, and
Manuel Stuehn <manuel dot stuehn at gmx dot net> verified it is OK
on that architecture now.
Also included now the "AVR COFF beta" patch that allows avr-objcopy to
generate AVR (extended) COFF files. Note the beta state (which only
affects this conversion though).
This commit also fixes a minor pkg-plist problem noticed by kris.
