Could you precisely tell what you see? I did this in qemu linux user
for i386 (version 0.10.5):
$  /usr/local/qemu/bin/qemu-i386 -strace ./myexecve /bin/ls

4 last lines showed:
20693 execve("/bin/ls",{"/bin/ls","-l","-s",NULL})total 16
8 -rwxrwxr-x 1 mulyadi mulyadi 5320 Aug 26 14:41 myexecve
4 -rw-rw-r-- 1 mulyadi mulyadi  428 Aug 26 14:41 myexecve.c
4 -rw-rw-r-- 1 mulyadi mulyadi  622 Aug 26 14:39 myexecve.c~

As you can see, it is executing /bin/ls, not qemu-i386.
