That is failing in haddock, which is trying to compile
ghc-internal in --make mode (as opposed to hadrian which
compiles using one-shot mode)

To reproduce, you can build haddocks using

   hadrian/build --flavour=release docs --docs=no-sphinx

the --docs=no-sphinx part is optional, it avoids polluting
your output with building sphinx docs for the ghc users
guide.
