I should add that a slightly more normal thing to see is that a
function has a defknown and a define-vop form for it in one of the
files in the compiler/target dir.  See for example FLOATING-POINT-MODES
(again, use find and grep -i)

I first ran into this porting to Alpha, when I was missing a defknown
and VOP (these tend to be defined per-backend) and actually _did_
manage to get an infinite loop ...
