--- Comment #1 from Alan Modra  ---
The default disassembly dialect is currently power9 with PPC_OPCODE_ANY
enabled.  So in cases where an opcode disassembles differently between power9
and some other cpu, the power9 variant is chosen, and when there is no power9
insn for a given opcode but there is a valid insn for some other cpu then that
other cpu insn is displayed.  This means that people can often use objdump to
disassemble without specifying -M.

Your code selects a fairly generic arch/mach combination and doesn't set
disInfo.disassembler_options, resulting in the default dialect.  See
ppc-dis.c:powerpc_init_dialect.

Strip is not supposed to touch the dynamic symbol table, .dynsym.

> Is checking forced_local enough?
See elflink.c:elf_link_output_extsym local_bind.

On second thoughts, don't look at elf_link_output_extsym.  bind_local there
can't be right since it's too late to make any decision different to that done
by _bfd_elf_link_renumber_dynsyms.
