cc/gcc: fix complibs dependency

Since the gcc configuration changes, the way to select the
dependent companion libraries has changed. The addToolVersion
script was not updated to match, and a new gcc version was
added with this script.

Fix the gcc version; the script will be updated in a subsequent
changeset.
