This question is important for me to. I'm running OE on linux-x86_64 
machine and want to build ARM toolchain for linux-x86 machine. I've 
asked about it on #irc and CruX| gave me config for building mingw32 
toolchain, it's in attachment and maybe it'll be helpful for you. 
Unfortunately, I couldn't adapt this config for my task, OE tries to 
build mingw all the same.

It would be great if someone explain how to build canadian cross SDK. I 
haven't found nothing helpful about it neither in documentation nor in 
ML archives but it is very important question I think.
