Improve make report with extra test arguments

Recently we have add the capability to adding extra compilation options
for running GCC testsuite, but it seems not handle well on the `make report`
part, it will ignore extra compilation options, and then...combine
multiple report together.

Now it will put in two different line, and the extra compilation options
will listed in follwoing line, here is example output here:
