Latest Git kernel doesn't compile because of the LINUX_VERSION_CODE issue

[Christian Zigotzky]

Hello,

I tried to compile the latest Git kernel today. Unfortunately it doesn't 
compile.

Error messages:

   CC      arch/powerpc/kernel/udbg_16550.o

I have found the bad commit. It's "Merge tag 'kbuild-v5.12' of 
git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild" [1]

The changes in the Makefile (a/Makefile) are responsible for the 
compiling errors. [2]

I was able to revert this bad commit. After that it compiled without any 
problems.

Could you please compile the latest Git kernel and confirm this issue?

Thanks,
Christian
