pc-bios/s390-ccw.img: Fix build
Since
commit a9c87304b76d ("build-sys: fix building with make CFLAGS=.. argument")
pc-bios/s390-ccw.img build might fail with
--- snip ---
main.o: In function `virtio_setup':
qemu/pc-bios/s390-ccw/main.c:117: undefined reference to `__stack_chk_fail'
--- snip ---
Changing the CFLAGS to QEMU_CFLAGS does the trick. We also need to
add -fno-strict-aliasing as this was filtered out.
