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.
Upgrade binutils to a recent snapshot, since this is a prerequisite
for the remaining ports.
Unfortunately, sources.redhat.com frequently purges older snapshot
tarballs, thus i gotta keep the one to use here around privately.
