Henry D. Case cb443468e8 Makefile improvement
Following things where added/changed:
* Builds correctly tls-tris. Previously go had a problem with
  a symbolic link resulting in not building tls-tris at all. I've
  used `rsync' instead.
* Can build for selected platform with "ARCH=platform make -f Makefile"
* Possible to build from any directory. Previously ``cd _dev; make``
  was required, it's possible to ``cd /whever/you/want; make -f /tris/Makefile``
