[csw-maintainers] Determining the architecture of a binary

[Maciej (Matchek) Blizinski]

I'd like to write a new check, to make sure that the actual binaries
inside a package match the architecture declared in the pkginfo file.
Unfortunately, the file command's output is not as reliable as I'd
like it to.  For instance, on build8s, it can tell when a binary is
i386, but it doesn't say the same about an amd64 binary.

| cut -d: -f2
        ELF 32-bit LSB executable 80386 Version 1, dynamically linked, stripped

        ELF 64-bit LSB executable Version 1, dynamically linked, stripped

We don't have our own, up-to-date file (or gfile), do we?

Is there a better way of determining binary's architecture? (/usr/ccs/bin/dump?)
