toolchain build happens in a sequence due to catch 22 it has to get
itself bootstrapped.
In a better world when staging is always packaged then gcc-initial
would create packages
which would be obsoleted by gcc-cross.

yes but for that you need to have the notion of toolchain is not being
build from scratch and in
other case when you have already bootstrapped it. This state
information needs to be saved somehow
obsoleting package feature in dpkg or bitbake would help in this
regard when it sees that gcc-cross is
already installed it would replace all gcc-cross-initial and
gcc-cross-intermediate references with gcc-cross


 Another option would be to install them with

I think if there
