    Useful for when people want to try some version of the perf tools and don't
    wants to download the kernel tarball.
    
    Here is a session using this new target:

        perf-tarbz2-src-pkg - Build perf-2.6.35-rc1.tar.bz2 source tarball
      [root@emilia linux-2.6-tip]# make perf-tarbz2-src-pkg
