Supports native builds on aarch64 machines. Supports making a 64-bit build via either cross compiling, or on aarch64 machines. Both options require the addition of --aarch64 to the command line, otherwise 32-bit libraries will be built. Cross compiling requires the aarch64-linux-gnu- compile tools to be installed (packages gcc-5-aarch64-linux-gnu and g++-aarch64-linux-gnu on Ubuntu).
