Here is the patch for the binutils 2.7. It allows the support for the
aout format. And there is also a very little but very important patch
for the opcodes lib. Currently this library was not able to
disassemble somthing, because I forgot to give the architecture
define. (That means, none of the binutils could use the --disassmemble
switch).
This is the same problem with the opcodes lib in the gdb 4.16 sources,
but I have loocked in the sources and saw, that gdb calls directly
the i386 disassembler, so there is no need for fixing it.
