util/xcompile/xcompile: set up for aarch64

The tools for aarch64 on ubuntu are called
    aarch64-linux-gnu-*
    The type is
    elf64-littleaarch64

This now finds the right files for building on aarch64

This has only been tested on ubuntu saucy; the aarch64 toolchain
    is in a very ill-defined state on most distros.
