Any ideaNo, sorry. I've just tried it again and couldn't find any problems with my gcc-8.1 binaries building either sparc32_defconfig or sparc64_defconfig.
Interesting. With sparc64-linux-gcc (GCC) 8.1.0 from kernel.org: make ARCH=sparc64 CROSS_COMPILE=sparc64-linux- allmodconfig make ARCH=sparc64 CROSS_COMPILE=sparc64-linux- arch/sparc/kernel/sys_sparc_64.o results in: ./include/linux/syscalls.h:233:18: error: 'sys_sparc64_personality' alias between functions of incompatible types 'long int(long unsigned int)' and 'long int(long int)' [-Werror=attribute-alias] and many more. Presumably this is due to arch/sparc/kernel/Makefile:ccflags-y := -Werror Guenter
