So why not have -i686, -k7 etc for packages where it does make a 
difference? We already do this for kernel and to some extent for libc6. 
Compression libs are used often in the background, and some rendering or 
3d stuff would definitely benefit and be used if falling back when no 
fancy graphics card is present. What else? Encryption libs?

Why not auto-detect processor type on install, and choose a handful of 
key k7 686 or whatever other sub-arch packages?
