I found this same problem some time ago, when I adopted libelf.
That time it was make which depended on libelf0, and Manoj found
that it wasn't needed at all. It was just an artifact introduced
by configure. In short, configure looks for /usr/include/elf.h ,
and if it finds that file, it adds "-lelf" to the gcc flags.
As elf.h is unrelated to libelf in Linux systems (I don't know
about it in SVR4 or Solaris, from where that library was ported),
this test is broken for Linux.
The only package I know that really uses libelf is the ELK, for some
manipulations with loadable modules. (Even that may be done with some
other library, but I have not found it yet).
