I have been using something along the lines of this:

However, I am very with it and the other places where I've had to do this,
such as install. I was considering a couple tweaks to the wrappers to do
auto detection of formats. Things like size, nm, strip, strings, etc can
look at their files to see what format they are.
This was the nice thing about having the binutils stuff reading a.out, it
didn't matter what sort of file a utility was give, it just worked. (or
didn't, as the case may be with the stale a.out binutils support.)
Cheers,
-Peter
