They do, as far as I remember.  I use this in the code of my library (libcwd):

      // Throw away useless or meaningless symbols
      asymbol** se = &symbol_table[number_of_symbols - 1];
      for (asymbol** s = symbol_table; s <= se;)
      {
        if ((*s)->name == 0 || ((*s)->flags & (BSF_LOCAL|BSF_GLOBAL|BSF_FUNCTION|BSF_OBJECT)) == 0
            || ((*s)->flags & (BSF_DEBUGGING|BSF_SECTION_SYM|BSF_OLD_COMMON|BSF_NOT_AT_END|
                               BSF_CONSTRUCTOR|BSF_WARNING|BSF_INDIRECT|BSF_FILE|BSF_DYNAMIC)) != 0
            || ((*s)->flags == BSF_LOCAL && (*s)->name[0] == '.')       // Some labels have a size(?!), their flags seem to be always 1
            || bfd_is_abs_section(bfd_get_section(*s))
            || bfd_is_com_section(bfd_get_section(*s))
            || bfd_is_ind_section(bfd_get_section(*s)))
        {
          *s = *se--;
          --number_of_symbols;
        }
        else
        {
          function_symbols.insert(function_symbols_ct::key_type(*s, !bfd_is_und_section(bfd_get_section(*s))));
          ++s;
        }
      }

Note the comment that I added there.  I added that when I still had a
"(*s)->value == 0" before it, even.

And yes, I DO use symbols that have BSF_LOCAL set!
