    - Add build support for gcc10 to HPC build (bsc#1174439).
    - Add openmpi4 flavors.
    - Add Fix-code-to-be-python3-compliant.patch:
      * Remove python2 code and dependencies.
      * Removed & Automated: fix_python_shebang.patch
      * Make python3 the default for TW and SLE/Leap 15
    - Do not mark template files for HPC as %config.
    
    - Change 'Requires:' to other HPC packages to %requires_eq to depend
      on the exact version. This should take care of HPC packages ignoring
      proper ABI versioning.
