You need to create a crosssdk/cross-canadian recipe that copies the binary 
toolchain into the right SDK location(s).  Using external-csl-toolchain (or 
similar) as a guide.

Yes, I have external-cs-toolchain.bb, and 
external-cs-toolchain-cross-canadian.bb, which is based on the former.

(most of it is generic, so a single ".inc" version used by both should be 
possible as well..)
