this would mean that if you need to use -dev files then you have to 
build target gcc. Have you looked into possiblity of removing these 
duplication from target gcc recipe instead ?

We may not want to build target gcc. Right now the libstdc++ package
will come from gcc-cross and dev packages will come from gcc target
recipes.

Look into why -dev file is not populated properly instead.
