When building perf out of tree:
$ make perf-tar-src-pkg
$ tar -xf perf-<ver>.tar -C /tmp
$ cd /tmp/perf<ver>
$ make -C tools/perf
you get this warning message:
make[1]: *** No rule to make target `kernelversion'. Stop.
Fix it by saving the perf version in the tar file and using that for the
out of tree builds.
v2: removed short form request and fixed up version string from usual output.
