Log:
  Make lex a bootstrap tool when cross-building on recent 13-CURRENT.
  
  The import of flex 2.6.4 into -CURRENT changed the type of yy_n_chars
  in the lex skeleton from yy_size_t to int, which breaks the build of
  binutils/ld when using the host copy of lex.
  
  ldlex.c:3216:3: error: incompatible pointer types passing 'int *' to parameter
        of type 'yy_size_t *' (aka 'unsigned long *')
        [-Werror,-Wincompatible-pointer-types]
    ...YY_INPUT( (&YY_CURRENT_BUFFER_LVALUE->yy_ch_buf[number_to_move]),
       ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  
  This is a direct commit to stable/11 since binutils/ld has been removed
  from -CURRENT, and it would require a different fix there since the
  bootstrap tool version of lex would also cause breakage.
