_start is called with the following registers initialized:
r1 null stack frame
r3 argc
r4 argv
r5 envp
r6 auxiliary vector. ignored.
r7 function pointer to jump to when main() exits. If
this is non-zero, it should be registered with atexit().
Linux always (?) sets r7 to NULL, so it is not implemented
here.
