I had something similar a few days ago, though I don't remember exactly
which setup it was on. Does the following commit help in your case?

commit fa2418539b4ac2cb1352948f68da08890cec7774

  Fix build error in staprun_funcs.c when HAVE_ELF_GETSHDRSTRNDX is not set.
  
  Mark find_section_in_module arguments unused when HAVE_ELF_GETSHDRSTRNDX
  isn't set.

Or do you need more than that?

Cheers,
