perf buildid-list: New plumbing command
With this we can list the buildids in a perf.data file so that
we can pipe them to other, distro specific tools that from the
buildids can figure out separate packages (foo-debuginfo) where
we can find the matching symtabs so that perf report can do its
job.
E.g:
[acme@doppio linux-2.6-tip]$ perf buildid-list | head -5
