      Description of problem:

      The GCC binary version provided by DTK does not match the running kernel in OCP 4.13 nightly

      Version-Release number of selected component (if applicable):

      4.13.0-0.nightly-2023-03-28-132111

      How reproducible:

      Check the '/proc/version' and 'rpm -qa | grep gcc' while running DTK in a pod in 4.13 nightly cluster

      Steps to Reproduce:

      1. Run pod : 
      oc run pod --image=quay.io/openshift-release-dev/ocp-v4.0-art-dev@sha256:9560ae2bee00c6fc10228c338fbcbcf5bdb9eaac604f7484936694513f6f4894 /usr/sbin/init
      
      2. oc rsh pod/pod
      3.
      

      Actual results:

      Kernel was built with gcc 11.3.1 while the provided binary version is 11.2.1
