ELF linker code does it for us.

gc variety, since we do our own .got handling.

dynamic section short-cuts. Localise vars, and delay setting.
Handle unknown relocs in main switch statement. Replace ugly
complicated tests for unresolvable relocs with a simple direct

before allowing an undefined sym in a shared lib. Do R_*_DS tests
after main switch, when we've set addend. Do non-addend insn
tweaks before main swithc. Ignore input_section->vma when
calculating reloc offsets as it's always zero. Rewrite dynamic
reloc handling. Consolidate R_*_HA handling. Handle more relocs.
(ppc64_elf_finish_dynamic_symbol): Remove DEBUG code. Make use
of dynamic section short-cuts. Reorganise .plt handling code.
