Re: 440 ebony patch seems to have broken 85xx build on powerpc.git

Nothing is telling GCC what CPU to compile for, so it
will just use the compiler's default, which very likely
is not what you want. =A0For files that will only ever
be used on 440, the correct flags are -mcpu=3D440 -Wa,-m440 .

We could add that to the per-file flags already, right?

I think it should really use -mcpu=3Dpowerpc on all files.
The problem that Dave saw was the result of using a compiler
that defaults to -mcpu=3D8540, which uses instruction that
don't work on 440.

The common files really need to be built with -mcpu flags that
make the code work on any system if you want to be able
to use just a single boot wrapper binary for all.
