Hi Alp,

Just confirming now but it seems its https://gitlab.haskell.org/ghc/ghc/commit/e529c65eacf595006dd5358491d28c202d673732 where the breakage came in ("Remove all target specific portions of Config.hs" @John Ericson).

        Hello!

        Could you create a ticket about this with all the relevant
        details (OS X version, boot ghc version, commit, hadrian
        command, etc), and the 'hadrian' label? You should even feel
        free to mention @snowleopard and @alp there.

        Cheers

        I can replicate this on multiple machines and different

        Any ideas?
