I think I'm surprised in general that no language targets the Go runtime. A ML built on Go could probably be popular, lots of people would like features from it.
Not exactly bytecode but Hy https://github.com/hylang/hy is a dialect of Lisp that compiles to Python.
Hy actually compiles directly to Python AST, not to Python. For a Lisp that compiles to Python, see Hissp: https://github.com/gilch/hissp
I don't think this is necessarily a matter of popularity or maturity. I don't know of languages that compile to Python bytecode, either. In Python's case I suspect the VM is so optimized for Python that it makes an inflexible target for other languages: I don't know enough about this subject to say whether that's the case for Go as well.
