    PR21441, Unnecessary padding of .eh_frame section

    Until all .eh_frame sections have been edited we don't know their
    sizes.  So it isn't possible to properly decide whether a non-empty
    .eh_frame section follows a given section until editing is complete.

        * elf-eh-frame.c (_bfd_elf_discard_section_eh_frame): Don't add
        alignment padding here.
        * elflink.c (bfd_elf_discard_info): Add .eh_frame padding here
        in a reverse pass over sections.
