Yes you are right.
The rule creates two targets, should it create also two test-result 
files? The attached patch generates the second test-result file as a 
copy of the generated one.
Thus the testsuite can rely on the existence of the test-result files
regardless of which target has triggered the rule.

Is this the right way?
What is your idea?
