I would be more worried about always remembering to set the correct
compiler for each target. This is something that I think you must
automate yourself.

I doubt this will happen - but you could of course patch emerge to do
it.

I suggest that you write a small wrapper script instead, and create a
new configuration file where you store the required gcc version for
each target. Make sure to put the full tuple with version number in
there and not the gcc-config index, which changes whenever you add or
remove a compiler version on the host.
