What's your actual test config here? Because when I try make ARCH=sh
allmodconfig; make ARCH=sh it dies in arch/sh/kernel/cpu/sh2/setup-sh7619.c with:

./include/linux/sh_intc.h:100:63: error: division 'sizeof (void *) / sizeof
(void)' does not compute the number of array elements [-Werror=sizeof-pointer-div]
  100 | #define _INTC_ARRAY(a) a, __same_type(a, NULL) ? 0 : sizeof(a)/sizeof(*a)

(Which isn't new, lots of configs won't compile off x86 and arm. I'm not sure
allmodconfig is picking a sane/actual cpu/board combo?)

What actual configuration are you trying to build?

P.S. Also my ssh cross gcc is 9.4 so I may need to build gcc-11 to see the
error, but I thought I'd try to reproduce the easy way first...
