Instead of pulling in various OpenCL runtimes, only depend on
eselect-opencl and an OpenCL ICD loader (dev-libs/ocl-icd) in order
to provide hardware-independent header files and libraries for
OpenCL-aware software to build against. Actual runtimes are now simply
suggested to the user via a postinst message.
