With the latest commit once butter has been built using make, it can then be built usinf butter! The only slight problem is that I haven’t yet thought how to get rpath into the link for the executable, so it then complains about a missing library. Also the notion of building a static library as well as a shared doesn’t seem to work, but I’m hopeful that’s not much.

I’ll do some more work and try and also figure out how we can do clean. Then I can try it out on a few more challenging builds and start to iron out the kinks.
