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
