Have elf_link_add_object_symbols return bfd_error_wrong_format

[Nick Clifton <nickc at redhat dot com>]

Hi Guys,

  I am applying the small patch below to make
  elf_link_add_object_symbols() return the error code
  bfd_error_wrong_format instead of bfd_error_invalid_operation when
  it encounters an input file in the wrong format.

  This was causing me some headaches trying to understand why a link
  command line was not  working when all it would say was that the
  operation was invalid.

Cheers
  Nick

	output format.
