I think the symbols are OK as is. _bfd_elf_get_synthetic_symtab has
*s = **p->sym_ptr_ptr;
s->section = plt;
s->value = addr - plt->vma;
s->name = names;
ie. flags will be set from the destination sym for synthetic plt syms,
making the synthetic sym BSF_GLOBAL or BSF_LOCAL. The ppc64 code does
similarly. So I think your gdb patch should simply leave the synthetic
sym flags unchanged.
