	* config/rs6000/rs6000.c (rs6000_option_override_internal): Initialize
	toc_label_name unconditionally.
	(rs6000_emit_load_toc_table): Call ggc_strdup on toc_label_name for
	SYMBOL_REF string.  Use toc_label_name instead of constructing
	LCTOC1.
	(rs6000_elf_declare_function_name): Use toc_label_name instead of
	constructing LCTOC1.
