configure: Fix support check for response files.

In failing to escape the '-o' in '-o\nconftest\nconftest.o\n' argument
to printf, the writing of the arguments response file always failed.

The fix is to pass the arguments after `--` so that they are treated
positional arguments rather than flags to printf.

Closes #23435
