Don't know enough about BitBake / OE to really comment on the problem 
directly.  I'm not trying to use an external toolchain.  I decided I'd rather 
fix the toolchain in OE than try to use an external toolchain.

I'm attaching my local.conf file for the AT32STK1000 board.  Of course, until 
I get the rest of my toolchain patches submitted, it may not help you out too 
much.  I think with what's currently in org.openembedded.dev, it will at 
least build a file system that'll boot until it gets to init, and then 
segfault.

Watch out for the PRJROOT variable I used in it.  I have a script I source 
when I start working on my project that sets this environment variable.
