There happens to be wide community consensus around a single Haskell compiler, GHC, at the moment, but that's a contingency and there are some other compilers, interpreters, and stuff like GHCJS. Profiling and debugging support is a feature of GHC (and other implementations), not of the language standard. Common Lisp has unified packaging and FFI and stuff through various community projects like ASDF and Quicklisp. If you're talking about Lisp in the general vague sense of "Lisps" then there can't be general interoperability because that umbrella term covers lots of very different languages with no formal common ground.
