[Qemu-devel] [NOTFORMERGE PATCH v2 23/23] Missing symbols when building with --disable-tcg

["Philippe Mathieu-Daudé" <philmd@redhat.com>]

While it might be normal to disable PSCI on KVM, I doubt the
VFP helpers are correct ;)

Anyway this allow to link the binary and run a KVM guest.

Tested using:

  $ make pc-bios/edk2-aarch64-code.fd
  $ dd if=/dev/zero of=flash1.img bs=1M count=64
  $ aarch64-softmmu/qemu-system-aarch64 \
    -nographic \
    -enable-kvm \
    -M virt,gic-version=3 \
    -cpu host \
    \
    -pflash pc-bios/edk2-aarch64-code.fd \
    -pflash flash1.img \
    -drive if=none,file=bionic-server-cloudimg-arm64.img,id=hd0 \
    -device virtio-blk-device,drive=hd0 \
    \
    -netdev type=user,id=net0 \
    -device virtio-net-device,netdev=net0
