Bug #2376: determine real cause of ldd crash

Problem: ldd core dumps in specific cases within RTLD

To reproduce:
> cd /usr/pkgsrc/audio/arts
> bmake install
> ldd /usr/pkg/bin/artswrapper

It dumps within rtld reading digest notes.  That's because the obj pointer has a null value even though it was just created (signal 11).

Trying to step through with gdb will result in a "signal 5", stopping at ldd.c line 205, right after a fork.

I need some help determining if the problem is ldd.c or something in the kernel.  I don't think rtld is really at fault here, although I'm not confident about the TLS/resident part.
