    tools/elfutils: enable parallel building
    
    There are multiple subdirectories for elfutils
    and more than one is not dependent on another,
    so enabling parallel building can save time
    if multiple cores are available.
    
    The change in build time for the package
    is as much as 20% when cores are not in use by other jobs.
