I found an unrelated bug.  When I tried to build perf out of tree after
'make perf-targz-src-pkg' it cannot get any version number.

      GEN common-cmds.h
      * new build flags or prefix
  make[1]: *** No rule to make target `kernelversion'.  Stop.
  PERF_VERSION = 
      ...
      AR libperf.a
      LINK perf

  $ ./perf --version
  perf version 


It looks like we should save and pass the result of 'make kernelversion'
to the tarball.

Thanks,
Namhyung
