We should in theory already be able to do that through vardie_from_symtable().

See dwflpp::literal_stmt_for_local():

      // If it is an external variable try the symbol table. PR10622.
      if (dwarf_attr_integrate (&vardie, DW_AT_external, &attr_mem) != NULL
          && vardie_from_symtable (&vardie, &addr_loc.number) != 0)

That should trigger, since I see:

46983: ffffffff81b89880      0 NOTYPE  GLOBAL DEFAULT      ABS jiffies

But it doesn't since vardie_from_symtable() has:

      if (symname
          && ! strcmp (name, symname)
          && sym.st_shndx != SHN_UNDEF
          && GELF_ST_TYPE (sym.st_info) == STT_OBJECT)

So, we need to be a little more creative and also allow NOTYPE?
