Newer versions of ccache use cmake for the build, so some of the logic in `make/devkit/Tools.gmk` had to be updated to support cmake based components.

You need to re-state the `/issue add JDK-8344272` command since Skara bots ignored it the first time around due to the PR title... (One could argue that this is a bug in Skara)
