Hello Renaud,
I reacted too quickly.
- It must have been changed for the 10.x compiler.
- The old code should still be there, but you need a certain argument.
- I think the simplest is to dig in the ./gcc/config/rs6000/ directory,
have a look at the *.md-files there, analyze the differences between
the 9.3.0 and 10.0.x version
of these files, and from there find out what flags you need.
Best Regards,
Henri.

Thanks Henri.
Just found out that if I remove the argument -mcpu=8540 from the arch/powerpc/Makefile then the mtcrf instructions is used instead and the system boots.
I will have to dig in the compiler to see what the consequence of this and if this is a possible solution.
