The subdirectories of libraries are currently listed as dependencies of the library. If you look at the actual symbols they contain, the opposite is true. For all of the bdevs, event subsystems and other library directories, the subdirectories actually rely on symbols contained in the parent directory. If we want to create the proper inter-library dependencies in SPDK at compile/link time, then we need to respect the order of these symbol dependencies when executing make (e.g. make libspdk_event.so before libspdk_event_bdev.so). Otherwise we create a loop of dependencies in the make system.
