Hello Philippe,
Apologies for the long delay.

Not as basic as I had thought ... but let's see:

Well, for now there isn't a documented way to do this easily with
Libtool, but I think there should be. So below is a script to achieve
it. Please try it and report how it fares; it should be fairly portable
but I have not tested it much at all, and it does not work with
uninstalled program wrappers yet.
I'm not yet sure how a good inclusion of the functionality into libtool
proper would look like. Similar stuff could be provided for stripping,
and maybe objdump... maybe a new --mode? Thoughts?
Cheers,
Ralf
