It was easy enough to build the bare metal debugger outside OE.  Just seems 
like you should be able to build this with OE, too.  It seems like it might 
need a separate .bb file to pull it off.  Not exactly sure how you'd force 
bitbake to use a different target setting.  Maybe setting the TARGET_OS to be 
blank in the bitbake file?

From the avr32linux wiki entry on kernel debugging:
avr32-gdb (the standalone debugger) or avr32-linux-gdb. Preferably the former 
since it has the ability to read and write system registers.
