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
