Aha.  Right, because this config forces -mspe it requires one of these
CPUs.

You can use a powerpc-linux compiler instead, and everything will just
work.  These CPUs are still supported, in all of GCC 9 .. GCC 12 :-)

Ok. I can use different "generic" powerpc compiler (It should work fine
as you said, as it has also -mcpu=8540 option). But I think that
compilation of kernel should be supported also by that gcc 8.5.0 e500
compiler.

That linuxspe compiler you mean.  Sure, why not, the more the merrier,
as long as it doesn't get in the way of other stuff, I won't protest.

But please don't confuse people: you are talking about a
powerpc-linuxspe compiler, not e500, which is supported just fine by
current GCC trunk still, and does not have such limitations :-)
