    testsuite: handle-multiline-outputs must allow both cc1 and cc1.exe
    
    Prior to 14-2027-g985d6480fe5, the input text had the file extensions
    pruned. In 14-2027-g985d6480fe5, due to the move of the call, the
    pruning is never done. This change restores the pruning of the file
    extension to allow multiline test to pass on both Windows and other
    platforms like Linux.
    
    gcc/testsuite/ChangeLog:
    
            * lib/multiline.exp: Added pruning of .exe.
