m68k: Remove inline strlen() implementation
GCC can replace a strncat() call with constant second argument into a strlen + store, which results in a link error: ERROR: "strlen" [net/ipv4/ip_tunnel.ko] undefined! The inline function is a simple for loop in C. Other architectures either use an asm optimized variant, or use the generic function from lib/string.c.
