Good point. If gcc was the only one then yes it was relatively ok. But
here we are talking about gcc and some other packages which
have x86_64 for target architecture in their configure scripts. I
thought of writing a class for target arch mapping but the recipes
which
depend upon TARGET_ARCH in some way will need to be taken care of. If
this approach sounds reasonable I can try a bit more on amd64
