Drivers implementing a class of devices (for example, drivers/event)
depend on the associated abstraction library (lib/eventdev).
This dependency is expressed in the top level meson.build for this class
(drivers/event/meson.build).
As we are making more libraries optional, custom constructs referencing
the class dependencies in some drivers meson.build (event/dlb2) may break.
It would be possible to add more checks in those drivers meson.build but
it is more straightforward to not even consider a driver meson.build when
the class dependencies are not met.
