OK OK, I am convinced. Then how about this? If you prefer speed over
size, the the other option is to add

size_t strlen(const char *s)
return __kernel_strlen(s);

to arch/m68k/lib/string.c. On a related note, arch/m68k/lib/string.c is
built only in the CONFIG_MMU case, whereas asm/string.h is shared.
