Comment (by snowleopard):

 You can change the build directory via the command line using `--build-
 root=PATH` (or shorter `-oPATH`).

 Can you try this?

 {{{
 hadrian/build.sh -c -j4 --flavour=quick -o/playpen/ghc
 }}}

 This is documented here: https://github.com/snowleopard/hadrian#command-
 line-flags.

 We can also add support for specifying the build directory in
 `UserSettings` so that you don't need to specify it each time via the
 command line.
