Hello,

on 5.11 I can update the config with dummy-tools but in 5.12 it no longer
works:

make ARCH=powerpc CROSS_COMPILE=scripts/dummy-tools/ oldconfig
scripts/dummy-tools/gcc: unknown compiler
scripts/Kconfig.include:44: Sorry, this compiler is not supported.
make[1]: *** [scripts/kconfig/Makefile:63: oldconfig] Error 1
make: *** [Makefile:605: oldconfig] Error 2

I think the new copiler version checks in 5.12-rc1 don't work with dummy
tools.

Any idea which side should be adjusted?

Thanks

Michal
