This is reported at  http://kisskb.ellerman.id.au/kisskb/buildresult/14905002/

I still see it on sparc32 using gcc-12.2.0.

The compiler info vs. the sparc-allmodconfig is confusing IMO.
I am compiling with sparc-linux, not sparc64-linux.

The .config file says:
# CONFIG_64BIT is not set
CONFIG_SPARC=y
CONFIG_SPARC32=y
