Comment (by mfox):

 It is crazy that mine works with almost no problems and doesn't even seem
 to care about llvm versions. You can try my build of HEAD: https://s3-us-
 west-1.amazonaws.com/stack-aarch64/ghc-8.1.20160209-aarch64-unknown-
 linux.tar.bz2

 I built llvm 3.7 and clang using default options and installed to
 /usr/local from: http://llvm.org/releases/download.html

 I am still curious whether there is some hardware difference, if it comes
 down to an ubuntu vs debian thing or whether I just got lucky somehow.
