    stdio-common: Remove _IO_vfwscanf
    
    The symbol has never been exported, so no compatibility symbol is
    needed.  Removing this file prevents ld from creation an exported
    symbol in case GLIBC_2_0 expands to a symbol version which
    does not have a local: *; directive in the symbol version map file.
