libtracefs needs threads resulting in the following build failure since
its addition in commit b1dbd3f679:

To use this profiling tool, you should enable ftrace in your
|
|
kernel configuration. This command collect traces on your
|
|
target. You can analyse these traces on the target or on
|
|
the host via the gui "kernel shark"
