description:
port this to arm64, and maybe fix the other ports in the
MachineStackMarker.cpp.  i didn't compile i386, arm or
mips with this, but it has a chance of working vs the
existing freebsd-derived patch.

XXX: someone extend this to all our CPUs, please.  i
     only fixed the existing maybe claimed support.
