Thank you for your help. I'm newbie in OE and crosscompiling at all and 
may confuse some things.

Just now I've tried to build some not so simple as helloworld but not so 
complicated as kernel -- bc calculator. And I'd like to say that during 
configure stage it sets:
--build=i686-linux --host=arm-oe-linux-gnueabi --target=arm-oe-linux-gnueabi

Builded bc works fine on my board and this is normal, not canadian, 
cross build.
