Actually I do see something with i386 host running the aarch64 memory
test (although so far not with a armv7 host):

  ./qemu-system-aarch64  -monitor none -display none -M virt -cpu max -display 
none -semihosting -kernel tests/memory

Gives:

  Reading u64 from 0x40213004 (offset 4):....Error 0, 0, 0, 0, 250, 249, 248, 
255Test complete: FAILED
