Building the docs, again

[Simon Peyton Jones]

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?

Hello,

never mind, I figured it out---apparently the build targets were disabled for the `quick` flavor, which I was using.

Hello,

sometime ago, I asked if it is possible to build just the GHC docs, without building the compiler.  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.

> make html V=0

(then I interrupted it).

Also, in `mk/config.mk<https://na01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fconfig.mk&data=02%7C01%7Csimonpj%40microsoft.com%7Cf681d88b258e48157e2008d520a95302%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C636450833981966485&sdata=F9gkJnWKkFVjF0ZgraTEyQXPnOA4Id2lL7jhppN1mrc%3D&reserved=0>` I see this:
BUILD_SPHINX_HTML        = YES
