Added -D (--dynamic) option to nm and -T (--dynamic-syms) and -R

	(--dynamic-reloc) arguments to objdump.
	* nm.c (dynamic): New static variable.
	(long_options): Added "dynamic".
	(usage): Mention -D and --dynamic.
	(main): Add D to getopt string.  Handle -D by setting dynamic.
	(display_rel_file): If dynamic is non-zero, read dynamic symbols
	rather than normal symbols.
	* nm.1: Updated for -D (--dynamic) option.
	* objdump.c (dump_dynamic_symtab): New global variable.
	(dump_dynamic_reloc_info): New global variable.
	(dynsyms, dynsymcount): New global variables.
	(usage): Mention -R, -T, --dynamic-syms and --dynamic-reloc.
	(long_options): Added "dynamic-reloc" and "dynamic-syms".
	(slurp_symtab): If no symbols, return rather than exit.
	(slurp_dynamic_symtab): New function.
	(display_bfd): Handle dump_dynamic_symtab and
	dump_dynamic_reloc_info.
	(dump_symbols): Take new dynamic argument, indicating whether to
	display dynamic symbols.
	(dump_relocs): Move most printing into dump_reloc_set.
	(dump_dynamic_relocs): New function.
	(dump_reloc_set): New function, extracted from dump_relocs.
	(main): Add R and T to getopt string.  Handle -T by setting
	dump_dynamic_symtab and -R by setting dump_dynamic_reloc_info.
	* objdump.1: Updated for -R (--dynamic-reloc) and -T
	(--dynamic-syms) options.
	* binutils.texi: Updated for new nm and objdump options.
