These libraries have an (indirect) dependency on T, either by using the
logging module (which in turn depends on T), or through other includes.
The easiest is to depend on the logging module, which will fulfil also
the T dependency.
It would equally be feasible to use the utils target (which in turn
depends on log_headers), but this would necessitate to compile, and does
not seem to be necessary.
Add a simple RF emulator library with no real RF.
It only synchronizes the gNB with the real time clock.
It is to be used for stress test or benchmarking in phy-test mode.
