I have a proposal about the build without libtraceevent.
Now it disables many perf commands if it doesn't have the
library.  But part of sub-commands would work without it.

For example, perf lock contention has two different modes
one is to use tracepoints (using the libtraceevent) and
the other is just use BPF.  The latter should work require
anything from the libtraceevent so we can enable such
usecase.

Others like perf sched, kmem and so on might want to run
only record part like in a small embedded machine (without
libtraceevent).  Then we can copy the saved data to a host
and run the report or other sub-commands to analyze the
data (again, using libtraceevent).

Thanks,
Namhyung
