lib/string.c: In function 'strscpy':
lib/string.c:209:4: error: implicit declaration of function 'zero_bytemask' [-Werror=implicit-function-declaration]
     *(unsigned long *)(dest+res) = c & zero_bytemask(data);

Now seen upstream for all powerpc builds. Seems to be due to
'strscpy: zero any trailing garbage bytes in the destination'.
