I don't understand - we already have stap probe points in ld.so that
do this and we also have LD_DEBUG, which gives the ability to trace
ld.so activities the conventional way, i.e. by dumping to a file or
stderr.  Neither have anything to do with ldd.

I have kinda reconciled with this since I realized that we don't
already validate ELF binaries - I had misread the validations.
