LinuxTools builder: sccache isn't used #62753
Description
The compiler time of LinuxTool builds are nearly 4 hours, which is due to the lack of sccache not being used. I believe that PRs don't have access to the same environment variable group as the auto builds, which means they don't have configuration of which S3 bucket to use, which means sccache is likely defaulting to the local disk rather than reading from the network.
