Comment (by raichoo):

 I've tried what has been suggested on IRC but now I'm running into the
 following behavior:

 {{{
 hadrian: '/usr/home/raichoo/Sources/ghc/ghc/_build/stage0/bin/ghc' exited
 with
 an error:
 ghc: missing -B<dir> option

 * _build/stage1/rts/setup-config

 }}}

 Just running `/usr/home/raichoo/Sources/ghc/ghc/_build/stage0/bin/ghc`
 also reports `ghc: missing -B<dir> option`. Am I again missing something
 that's obvious here?
