Any reason not to remove CHRP too ?

OK, we can do that in a second step.

32 bits kernel on g5 were unuspported for ages and I announced the death
of that support long enough in advance. miboot works with plain vmlinux,
the only thing those miboot images are useful for is if you need a
compressed image due to lack of space and/or if you need an embedded
initrd. Hopefully, that should be trivial to add back though.
