Where it's been fixed? current git version of scripts/qemu-binfmt-conf.sh does not have 'preserved' option, and if the P flag is set when registering binfmt, the kernel will _prepend_ additional argv[0] element which is not expected by current linux-user/main.c code (so the tst.c example will be running with 3 args, not 2).
