Spot on! I ran it remotely and had a different qemu in my default path:

  $ qemu-x86_64 --version
  qemu-x86_64 version 2.7.0, Copyright (c) 2003-2016 Fabrice Bellard and the QEMU Project developers

I didn't notice but it yells at me during the test:

  qemu: Unsupported syscall: 332

Locally with this version it's much cleaner:

  $ qemu-x86_64 --version
  qemu-x86_64 version 6.2.0
  Copyright (c) 2003-2021 Fabrice Bellard and the QEMU Project developers
  $ make run-user | grep status:
  143 test(s): 141 passed,   2 skipped,   0 failed => status: warning

So we can keep it and blame my environment for that failure.

Thanks for checking,
Willy
