That's not really an unreasonable requirement. It would just be one
argument to a general function. But as has been pointed out, it's not
really required because a function can be written that examines the
_DYNAMIC table itself. If that function lives in another shared library,
it needs to take &_DYNAMIC as an argument from code in the library that
wants to know about itself.

Adding something to glibc would be trivial if an interface is chosen.
The Solaris `dlinfo' interface looks reasonable at a glance. I could add that.
