Do not choose a non-ELF format input file to hold the linker created GOT sections.

	PR 21884
	* elf32-i386.c (elf_i386_link_setup_gnu_properties): If the dynobj
	has not been set then use the bfd returned by
	_bfd_elf_link_setup_gnu_properties.  If that is null then search
	through all the input bfds selecting the first normal, ELF format
	one.
	* elf64-x86-64.c (elf_x86_64_link_setup_gnu_properties): Likewise.
