I think 32bit will be called powerpc-*-*-gcc and 64bit will be powerpc64-*-*-gcc
which is IMO readable. GCC based toolchains have their own idea of
multilib which isnt quite same as OE. So I think current solution is
better. As long as both compilers
are shipped in SDKs it should be fine. But I see the point where if
you have been
shipping single multilibbed toolchains then there will be a change the
way compilers
are invoked.
