Public bug reported:

The userspace LTTng library can also generate USDT (Userspace Staticly
Defined Tracepoints) probes for ust tracepoints. These allow tracing
lttng tracepoints with ftrace or eBPF tracers.,

Enabling this should be as simple as adding --with-sdt to the configure
options and adding systemtap-sdt-dev to Build-Depends:
