Public bug reported:
Since commit 92550b568d, the perf build for Ubuntu kernels does not link
to libtraceevent, and thus cannot perform any operations on tracepoints,
including processing perf.data files that contain tracepoint events.
This is a significant loss of functionality.
Attempts to utilize tracepoints fail with the following:
perf record -e skb:kfree_skb
event syntax error: 'skb:kfree_skb'
\___ unsupported tracepoint
libtraceevent is necessary for tracepoint support
