    bfd: drop unused elt_no
    
    GCC trunk recently had improvements to its -Wunused-but-set-variable which
    picked up that elt_no isn't used at all in the end.
    
            * archive.c (_bfd_compute_and_write_armap): Drop unused elt_no.
    
    (cherry picked from commit 11153b13a56dae4ddd068ccf812ebc295783edf9)
