PR26489, ASAN: ppc64_elf_size_stubs elf64-ppc.c:13389

Stub sections are inserted after sec_info is sized, so have higher ids.
Test flags that will exclude stub sections before looking at the
sec_info array.

	PR 26489
	* elf64-ppc.c (ppc64_elf_size_stubs): Test code_sec->has_toc_reloc
	and code_sec->makes_toc_func_call before sec_info[code_sec->id].
