Those utilities are required on the target system to start and stop tracing sessions. Analysis of the trace can be done on the host machine using the babeltrace utility. This utility is automatically built by Buildroot in $(O)/host/usr/bin/babeltrace, as a dependency of lttng-tools. However, there is also a lttng-babeltrace package for the target, if babeltrace on the target is interesting. If userspace tracing is desired, you need to enable lttng-libust. http://lttng.org comment "lttng-tools needs a toolchain w/ threads, dynamic library" depends on BR2_PACKAGE_LIBURCU_ARCH_SUPPORTS depends on !BR2_TOOLCHAIN_HAS_THREADS || BR2_STATIC_LIBS
