* elf64-ppc.c (ppc64_elf_relocate_section): When optimizing toctprel
tls, check that a TOC16_DS or TOC16_LO_DS reloc isn't pointing to a dtprel entry. Ensure TLS_LD DTPMOD reloc has a zero addend. Write got section for RELATIVE relocs. Fix wrong comment. Change condition under which dynamic relocs update the section contents.
