Or the maximum bitsize of its targets, as the problem also shows for 32bit tools
but who can handle 64bit objects.

It works, thanks (I suppose the work could also be done on objdump, to have a
coherent behaviour), but it breaks the purpouse H.J. Lu mentioned.
It's indeed not clear about what should be done, for multi-arch utils. Maybe a
switch ? (but it would become much more than a small patch, and I don't want to
have an argument with developpers)
