Link failure on aarch64 host:
  LINK    arm-softmmu/qemu-system-arm
hw/virtio/vhost-user.o: In function `vhost_user_postcopy_fault_handler':
/home/pm215/qemu/hw/virtio/vhost-user.c:1000: undefined reference to
`postcopy_request_shared_page'

I think this host is taking the "don't have userfaultfd" #ifdef
path in postcopy-ram.c, which doesn't define a stub
for the postcopy_request_shared_page function, but there's
no equivalent guard in vhost-user.c
