http://www.daemonology.net/bsdiff/ seems to maybe do what you want--
essentially diff should solve your problem, although I'm not too clear
on how that works on differently compiled binaries.
I also seem to recall there was a test function that returned different
results based on if the two files mentioned as arguments were identical,
but I can't recall offhand quite what it was.
