Explicit breakage vs. sparse warnings are two different things. It may
be that we can delete strstr() just like I did for atou() -- but in the
interest of doing the minimal change, I did just what was needed for
fixing the sparse warnings for strstr. I can test if it can be removed,
but it has the smell of generic-libc usage all over it...
