[OE-core] build stat output

[Nicolas Dechesne]

hi,

I am trying to make up some sense with the bitbake output at the end
of my build. I have enabled buildstats and buildstats-summary.

What do all these numbers mean? They don't quite sum up..

Sstate summary: Wanted 15 Found 9 Missed 12 Current 125 (60% match,
95% complete)
NOTE: Executing SetScene Tasks
NOTE: Executing RunQueue Tasks
NOTE: Tasks Summary: Attempted 592 tasks of which 576 didn't need to
be rerun and all succeeded.
NOTE: Build completion summary:
NOTE:   do_populate_sysroot: 99.5% sstate reuse(183 setscene, 1 scratch)
NOTE:   do_package_qa: 98.9% sstate reuse(89 setscene, 1 scratch)
NOTE:   do_package: 0.0% sstate reuse(0 setscene, 1 scratch)
NOTE:   do_packagedata: 98.9% sstate reuse(89 setscene, 1 scratch)
NOTE:   do_package_write_ipk: 98.9% sstate reuse(89 setscene, 1 scratch)
NOTE:   do_populate_lic: 99.5% sstate reuse(185 setscene, 1 scratch)
NOTE: Writing buildhistory

thanks!
