I know of one project at least, in development and undocumented, that
uses GHC's backend. However, it doesn't use the Core interface. Rather,
it uses an interface Mark Wotton and I wrote to the Stix layer of the
native code generator. This is around 3 abstraction layers further down

I'm pretty sure this hasn't changed. It is hard but not impossible. Lots
of magic though.
