[PATCH] gcc/toplev.c: Avoid to close 'asm_out_file' when it is 'stdout'

[Chen Gang]

'asm_out_file' may be 'stdout', so need check this case before close it.
Or 'stdout' may be closed -- since need not open 'stdout', either need
not close it.

ChangLog:

  * topleve.c (finalize): Avoid to close 'asm_out_file' when it is
  'stdout'.
