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.
