    util/xcompile/xcompile: try, and fail, to set it up for aarch64
    
    Not to be comitted until fixed.
    
    The tools for aarch64 on ubuntu are called
    aarch64-linux-gnu-*
    The type is
    elf64-littleaarch64
    
    I've added what I think ought to work but it fails to find it.
    
    One thing I've noticed is that gcc for the test .c file
    is only run AFTER the first instance of testas is run, which
    I don't understand. But the assembly source in /tmp that testas
    runs against, for aarch64, is a 0-byte file.
    
    This has only been tested on ubuntu saucy; the aarch64 toolchain
    is in a very ill-defined state on most distros.
