ldd should be a distinct tool that uses libelf, and provides deeper
introspection and options. This way we have a second implementation
of the loader rules in a cleaner and concise form that we can use
to double-check assertions about load order and cycle breakage,
and cross-check ld.so changes.

I have a half-written eu-ldd that I've started. I guess I should
contribute that to elfutils soon.
