IIUC, singeli is some tool that emits avx2-specific opcodes and the
singeli builds of cbqn use that somehw; I admit, I do not completely

Will simply adding (tunable? . #t) as a property be enough?  Also
related to the signeli thing, do we have the means to create special
build flows for tuned packages?
