The x86_64 build is broken (known issue). The maintainer of that target 
is working on it. However he's away on business right now, so he has 
less time to spend on it than normal.

Due to the nature of our project, we need to work from the HEAD of the 
Linux Kernel and LLVM project, which means things can break easily.

We should probably provide a config file which allows you to compile an 
eariler version of our project which does work.
