little nore about the reason would be nice ;-)
looks ok, but the python test is still failing,
the reason is the perf_counts struct objects and functions
bindings to util/stat.c object
Arnaldo,
I separated the 'struct perf_counts' into util/counts.c,
because I recall you did not want them in evsel.c,
please check attached patch.. it makes the python test
pass again (on top of Kan's change).
thanks,
jirka

Moving perf_counts struct and functions into separate object,
so we could remove stat.c object dependency from python build.
It makes the python code to be built properly, because now it
fails to load due to missing stat-shadow.c object dependency.
