linux: don't build gold as part of install-build-deps.sh
Now that it's in the tree we don't need to force everyone to build it. (Especially since the code to build it didn't put it in the path anyway.) Review URL: https://chromiumcodereview.appspot.com/9317085 git-svn-id: http://src.chromium.org/svn/trunk/src/build@121005 4ff67af0-8c30-449e-8e8b-ad334ec8d88c
