Says:
CONFIG_CC_VERSION_TEXT="powerpc64le-linux-gnu-gcc-10 (Ubuntu 10.4.0-4ubuntu1~22.04) 10.4.0"
Do you see the same issue with a newer GCC?
There's 12.2.0 here:
https://mirrors.edge.kernel.org/pub/tools/crosstool/files/bin/x86_64/12.2.0/
https://mirrors.edge.kernel.org/pub/tools/crosstool/files/bin/ppc64le/12.2.0/
Or if you can build in a Fedora 38 system or container, it has GCC 13.
cheers
