Add support to readelf for detecting and reporting Solaris specific section types...

	PR target/19983
	* readelf.c (get_solaris_section_type): New function: Returns the
	name of Solaris specific section types.
	(get_solaris_dynamic_type): New function: Return the name of
	Solaris specific dynamic types.
	(get_dynamic_type): Use get_solaris_dynamic_type.
	(get_section_type_name): Use get_solaris_section_type.
	(get_solaris_symbol_visibility): New function: Returns Solaris
	specific symbol visibilities.
	(print_dynamic_symbol): Use get_solaris_symbol_visibility.
	(process_symbol_table): Likewise.
