I used the latest test branch:

https://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux-next.git/log/?h=20211020-firmware-builtin

And I can't reproduce there, that build fails for another reason though:

ld.lld: error: undefined symbol: _printk
>>> referenced by io-acorn.o:(.text+0x38) in archive
>>> arch/arm/mach-rpc/built-in.a
make: *** [Makefile:1183: vmlinux] Error 1
make: Target '__all' not remade because of errors.
