+Subject: [PATCH] Makefile: fix build of io_uring on sh4
+
+SuperH compile currently fails with:

+/usr/lfs/hdd_v1/rc-buildroot-test/scripts/instance-0/output-1/host/opt/ext-toolchain/bin/../lib/gcc/sh4-buildroot-linux-uclibc/8.3.0/../../../../sh4-buildroot-linux-uclibc/bin/ld: t/io_uring.o: in function `submitter_fn':
+/usr/lfs/hdd_v1/rc-buildroot-test/scripts/instance-0/output-1/build/fio-3.19/t/io_uring.c:131: undefined reference to `arch_flags'

+collect2: error: ld returned 1 exit status
+
+Fix that by ensuring we have a stub arch.o with the necessary arch flags
