Did you try avr-objdump?

If you give objdump the --help option it will tell what architectures and
targets it was compiled for. From my linux box:

  $ avr-objdump --help
  <snip>
  avr-objdump: supported targets: elf32-avr elf32-little elf32-big srec 
symbolsrec tekhex binary ihex
  avr-objdump: supported architectures: avr avr:1 avr:2 avr:3 avr:4 avr:5

  $ objdump --help
  <snip>
  objdump: supported targets: elf32-i386 a.out-i386-linux efi-app-ia32 
elf32-little elf32-big srec symbolsrec tekhex binary ihex trad-core
  objdump: supported architectures: i386 i386:x86-64 i8086 i386:x86-64:intel 
i386:intel

Notice the difference.
