Fix name of thing

I triggered a build against my circle ci integration, through phab's build step interface. Let's see how it goes: (previously, it'd just blow up, trying to build and run things with -j9 on a 2 core box with 4GB of RAM).

It looks like switching to the ghc-diffs repo you created as a "staging" one for the Circle CI builds did the trick. Not sure how important the core detection logic was in making this work, but I suppose it is anyway better not to just blindly run with -j9.

I triggered a build from the phabricator interface, which resulted in this successful Circle CI build:
The Phab side is here: -- it is not yet rich in information about the build, but this is also the very first build that succeeds in this setup.
