Description 
The following code:

   while ((gelf_getdyn(data_dyn, t, &gd))) {
   .....
   }

will read one too many .dynamic entries - if you're lucky, the data within
the section that follows the .dynamic section will have a value that can be
interpreted as a DT_ flag :-)
Work Around 
Instead of the while loop, compute the number of dynamic entries (shdr.sh_size /
shdr.sh_entsize) and look at just that number of entries.
