  # Emulation on s390x platform is incredibly slow and memory demanding.
  # It seems that any executable with GHC RTS takes at least 7-8 Gb of RAM, so we can
  # run `cabal` or `ghc` on their own, but cannot run them both at the same time, striking
  # out `cabal test`. Instead we rely on system packages and invoke `ghc --make` manually,
  # and even so `ghc -O` is prohibitively expensive.
