showSamples.sh: Fix how we get gcc and version for showSamples.sh

I'm not even sure how the previous loop was supposed to work.
The config variables are not exported to the environment.
Now we properly get which cc we are using and grab the version to
display it correctly with the output of wiki-samples.
