    Commit dc4d7b37 (MIPS: ZBOOT: gather string functions into string.c)
    moved the string related functions into a separate file, which might
    cause the following build error, depending on the configuration:
    
    | CC      arch/mips/boot/compressed/decompress.o
    | In file included from linux/arch/mips/boot/compressed/../../../../lib/decompress_unxz.c:234:0,
    |                  from linux/arch/mips/boot/compressed/decompress.c:67:
    | linux/arch/mips/boot/compressed/../../../../lib/xz/xz_dec_stream.c: In function 'fill_temp':
    | linux/arch/mips/boot/compressed/../../../../lib/xz/xz_dec_stream.c:162:2: error: implicit declaration of function 'memcpy' [-Werror=implicit-function-declaration]
    | cc1: some warnings being treated as errors
    | linux/scripts/Makefile.build:308: recipe for target 'arch/mips/boot/compressed/decompress.o' failed
    | make[6]: *** [arch/mips/boot/compressed/decompress.o] Error 1
    | linux/arch/mips/Makefile:308: recipe for target 'vmlinuz' failed
    
    It does not fail with the standard configuration, as when
    CONFIG_DYNAMIC_DEBUG is not enabled <linux/string.h> gets included in
    include/linux/dynamic_debug.h. There might be other ways for it to
    get indirectly included.
    
    We can't add the include directly in xz_dec_stream.c as some
    architectures might want to use a different version for the boot/
    directory (see for example arch/x86/boot/string.h).
