[Buildroot] [PATCH 1/2] package/lttng-modules: enable CONFIG_FTRACE in kernel configuration

[Thomas Petazzoni via buildroot]

The build of lttng-modules will fail if the kernel does not have
CONFIG_TRACEPOINTS enabled. However, CONFIG_TRACEPOINTS is a
prompt-less option, and the most generic option that does enable
CONFIG_TRACEPOINTS is CONFIG_FTRACE.

In addition, CONFIG_FTRACE will also enable CONFIG_STACKTRACE, which
is needed on CPU architectures that don't provide the STACKWALK
mechanism in the kernel, as is the case on ARM 32-bit for example.

Therefore, let's enable CONFIG_FTRACE when building lttng-modules.
