Currently the SPL target is specified in a CPU-specific makefile
fragment.  While some targets may need something more complicated than a
simple target name, targets which don't need this shouldn't have to provide a makefile fragment just for this.

v2: Removed default target as it's been pointed out to me how existing platforms
cause the SPL to be built.
