PR15530, mark symbol in executables if it matches dynamic_list

Browse Source 
For powerpc64 as HJ did earlier for other ELF targets, and a tidy.

	PR gold/15530
	* elf64-ppc.c (ppc64_elf_gc_mark_dynamic_ref): Support
	--export-dynamic and --dynamic-list marking of symbols.
	* elflink.c (bfd_elf_gc_mark_dynamic_ref_symbol): Reorder
	cheap tests first.
