* Many files: Changes to avoid gcc warnings: Add ATTRIBUTE_UNUSED

	as appropriate.  Add variable initializations.  Add casts.
	* objdump.c (disassemble_bytes): Change j to bfd_vma.
	* readelf.c (process_syminfo): Change i to unsigned int.
	(display_debug_info): Change abbrev_number to unsigned long.
	(process_mips_specific): Change fcnt to size_t.
