Without this extra flag we can't distingish between stub functions and functions that happen to have address 0 (relative to __table_base). Adding this flag bit the base symbol class actually avoids growing the SymbolUnion struct which would not be true if we added it to the FunctionSymbol subclass (due to bitbacking). The previous approach of setting it's table index to zero worked for normal static relocations but not for `-fPIC` code.
