Hi, Pedro.  I looked into this a little further.  I think you just
need to extend this function in bfd/bfd.c appropriately:

int
bfd_get_sign_extend_vma (bfd *abfd)
{
  char *name;

  if (bfd_get_flavour (abfd) == bfd_target_elf_flavour)
    return get_elf_backend_data (abfd)->sign_extend_vma;

  name = bfd_get_target (abfd);

  /* Return a proper value for DJGPP & PE COFF (x86 COFF variants).
     This function is required for DWARF2 support, but there is
     no place to store this information in the COFF back end.
     Should enough other COFF targets add support for DWARF2,
     a place will have to be found.  Until then, this hack will do.  */
  if (strncmp (name, "coff-go32", sizeof ("coff-go32") - 1) == 0
      || strcmp (name, "pe-i386") == 0
      || strcmp (name, "pei-i386") == 0)
    return 1;

  bfd_set_error (bfd_error_wrong_format);
  return -1;
}
