 Take any set of modules with a loop broken by an hs-boot, and run `ghc
 --make -dynamic-too` on it. Suppose A.hs imports B.hs, which source
 imports A.hs-boot; then compiling these you will get
 `A.{hi,o,dyn_hi,dyn_o}`, `B.{hi,o,dyn_hi,dyn_o}`, and ONLY `A.{hi-
 boot,o-boot,dyn_hi-boot}`: `A.dyn_o-boot` is missing.
