I wouldn't call it a "decision", that would imply intent. The main
reason I explicitly list targets for llvm is to limit the CPU backends
to arches Fedora actually runs on (which itself is because I really
only care about llvmpipe, and am only touching llvm because it's in my
way). Had no idea there was a bpf backend, so never thought to enable
it.

llvm-3.7.0-4.fc2{3,4} are building now with the bpf backend enabled,
I'll create an update for F23 when it's built.
