You're not getting as far as any code in vg_syscall.S though. Don't
get confused by VG_(clone) as that has nothing to do with implementing
clone in the client program - it's used by valgrind to start the
background threads that it uses for handling blocking system calls.

Not exactly. The message you are getting comes from vg_syscalls.c
but the point is that clone is not like other system calls where
you can trivially implement it - it would require a substantial
amount of work throughout valgrind.
