After reading the tracepoints.txt documentation, I tried to
follow the instructions to run the sample, but just assigning
CONFIG_SAMPLE_TRACEPOINTS=m wasn't enough to generate the tracepoints
samples. I also need to set CONFIG_SAMPLES=y, otherwise nothing
happens.
So, this silly patch explicit says that CONFIG_SAMPLES should be set to
compile those files.

Actually raw tracepoints are deprecated. Both the documentation and the
samples should be removed, with maybe a few tidbits about the consumer
side moved to the trace_event samples because they can still be used
with them.
