* coffcode.h (coff_compute_section_file_positions): Keep the
	raw size safe.
	(coff_write_object_contents): Remember if it's a relocatable
	file.
	* libcoff-in.h (pe_data_type): New member 'has_reloc_section'
	* peicode.h (coff_swap_filehdr_out): Clear not-reloc flag
	if relocatable file. Swap out saved raw size.
