:same doesn't exist (in this context), where did you find that?
Anyway, negative dependencies (Conflicts/Breaks/Replaces) effect all
architectures and can't be limited to specific architectures currently [0].

How about alternatives instead of this Provides/Conflicts/Replaces stuff
to allow multiple loaders per architecture (and such an alternative is
architecture specific by design).

And could the virtual package maybe named 'opencl-loader-api-1' or
something?
