When cross compiling via LLVM, a target 'datalayout' and 'triple' must be defined or LLVM will generate code for the compile host instead of the compile target. * Add aarch64-unknown-linux-gnu target. The datalayout and triple lines were found by using clang to compile a small C program and -emit-llvm to get the LLVM IR output.
