PR24355, segmentation fault in function called from ppc_finish_symbols

Backport to 2.30, where the problem might be triggered by gc-sections
rather than inline PLT optimization as in the PR.

PR 24355
* elf32-ppc.c (ppc_elf_relocate_section): Don't call write_glink_stub
for local iplt syms with ent->plt.offset == -1. Remove ineffective
attempt at writing glink stubs only once. Correct plt.offset mask.

Fix a NULL pointer dereference in nm, when parsing a corrupt file.

PR 24168
* nm.c (print_symbol): Check for NULL contents of the sym_ptr_ptr
field.

x86: Disable GOT relaxation with data prefix

Since linker GOT relaxation isn't valid for 16-bit GOT access, we should
disable GOT relaxation with data prefix.

x86: don't mistakenly scale non-8-bit displacements

In commit b5014f7af2 I've removed (instead of replaced) a conditional,
resulting in addressing forms not allowing 8-bit displacements to now
get their displacements scaled under certain circumstances. Re-add the
missing conditional.
