    armv7: mark EABI compatibility symbols as used
    
    These symbols are not used anywhere in our C code, so
    when using GCC's link time optimization feature they
    will be dropped even though they're needed by libgcc.
    Hence we need to mark them as used so GCC does not stumble
    and fall over its own guts.
