linux-user/syscall.c:9860:17: warning: Call to function 'strcpy' is insecure as
it does not provide bounding of the memory buffer. Replace unbounded copy
functions with analogous functions that support length arguments such as
'strlcpy'. CWE-119
strcpy (buf->machine, cpu_to_uname_machine(cpu_env));
