Bug#796800: haskell-cryptonite: FTBFS on most architectures

This package fails to build on non-Intel architectures:

https://buildd.debian.org/status/package.php?p=haskell-cryptonite&suite=sid

I found I could build it on arm64 with this patch:

     CPP-options: -DARCH_IS_LITTLE_ENDIAN

   if arch(i386)



However, I don't think "arch" is the right way to detect endianness.
Some architectures come in little-endian and big-endian variants.

What's the right way? Perhaps "#ifdef ARCH_IS_LITTLE_ENDIAN" shouldn't
appear in Haskell source files, seeing as there are things like
Data.Endian and System.ByteOrder.

Of course, something like the above could be a viable temporary
work-around for most Debian architectures.
