More PowerPC64 ELFv2 --just-symbols fixes
I don't know what I was thinking here to omit the save of r2. Possibly I was looking at -msave-toc-indirect code at the time, where r2 is saved in the function prologue. * elf64-ppc.c (ppc_build_one_stub <ppc_stub_plt_branch_r2off>): Don't omit saving of r2 for ELFv2. Don't addi 2,2,0. (ppc_size_one_stub <ppc_stub_plt_branch_r2off>): Adjust to suit.
