It is quite confusing that we can be setting the same variable to different values in different places. It would also be quite helpful if we modified the Makefile to say `documentation build target is disabled` or some such, rather then going ahead and building the whole of GHC, only at the end to inform me that it doesn't know what is `html`. Maybe Hadrian will help here?

I was told to just run `make html`. This does not appear to work, the command seems to just start building GHC. What am I doing wrong? Here is the output I see, running the command from the root of the GHC tree.
