elf_getshstrndx is used by SystemTap but it is deprecated by commit
f189493154d0041deced00e6a99cc5426dc9d260 in elfutils. 

This results in systemtap build error.

The error is pasted below.

This comes from the following elfutils change:

commit f189493154d0041deced00e6a99cc5426dc9d260
Author: Ulrich Drepper <drepper@redhat.com>
Date:   Sat Jun 13 15:55:42 2009 -0700

    Add aliases for elf_getshnum and elf_getshstrndx.
    
    Sun in their implementation messed up the semantics of these functions.
    To get back to source code compatibility they asked for a solution.
    We simply add aliases for the two affected functions, named
    elf_getshdrnum and elf_getshdrstrndx.  The semantics remains the
    same.  Users of the old interfaces receive a warning for now.  In
    future we might make it impossible to link programs which request
    the old interfaces (binary compatibility will of course be maintained).

    * dwflpp.h: Check elfutils version, define elf_getshdrstrndx as
      elf_getshstrndx if elfutils 0.142 detected.
    * dwflpp.cxx (get_blacklist_section): Use elf_getshdrstrndx.
    * tapsets.cxx (probe_table): Likewise.
      (prepare_section_rejection): Likewise.
