The commands to run the compilation when printed with `-###` shows various 
irrelevant lines for the perf-training. Most of them are filtered out already 
but when configured with
`CLANG_CONFIG_FILE_SYSTEM_DIR` a new line like the following is added and needs 
to be filtered out:

`Configuration file: /etc/clang/x86_64-redhat-linux-gnu-clang.cfg`
