It wants to read back just written .xt.lit.plt section to rearrange it
a bit in the
following call chain:

main
  ldwrite
    bfd_elf_final_link
      elf_xtensa_finish_dynamic_sections
        elf_xtensa_combine_prop_entries

and obviously fails. This only happens when the result is dynamic object,
static linking completes successfully.
I don't see why this might be considered invalid behaviour, and rather
think that
the check in the dhcpcd configure script is wrong.
