There's a bug in cabal-arm where if cabal fails during the install function, the error is ignored and cabal-arm still returns 0.

I ran into this when using your ghc-cross-arm-cloud dockerfile, since the RUN cabal-arm install commands were all failures, but docker was ignoring the failures since they all returned 0, so the container started up, but was non-functional.
