Recipe for Atmel SAM-BA tool

This is an initial attempt at a recipe for SAM-BA

Request feedback on:
- handling host tcl and tk requirements (currently, the recipe assumes they are available)
- license type (I couldn't find an explicit license in the sam-ba distributable or Atmel website)
- handling non linux-x86 hosts (currently, the recipes assumes a linux-x86 host or ia32-libs is installed)
- installation location
