I rm -rf ~/0day and tried again but the failure I get is:

CALL scripts/checksyscalls.sh
<stdin>:1515:2: warning: syscall clone3 not implemented [-W#warnings]
#warning syscall clone3 not implemented

Even if I disable CONFIG_WERROR and COMPILE_TEST this still fails here
and so I can't even test compile the code in question.
