Fix bug in ldso/util/Makefile introduced when Erik added the readelf app.

It didn't show up if a previous install was done.  This would have been
fixed two days ago if the initial bug report had been anything close to
lucid.  :-(  Also changed ldconfig back to staticly linked and update the
README file.
