-hvf-accelerated aarch64 hangs when switching to big endian mode
-Description of problem:
-Trying to boot a big endian Linux kernel using the above command line on an M1 Mac Mini just hangs, there is not a single output.  However, by replacing `hvf` with `tcg`, the kernel boots up fine.  The kernel also starts if I use KVM acceleration on a Linux host system.
-Steps to reproduce:
-1. Build a Linux kernel for big endian arm64
-2. Try to boot it with -accel hvf on an M1 Mac
-3. Observe a lot of nothing happening  :-)
-Additional information:
-Sample run, TCG vs HVF
