m32r: add memcpy() for CONFIG_KERNEL_GZIP=y 



Fix the m32r link error:

    LD      arch/m32r/boot/compressed/vmlinux
  arch/m32r/boot/compressed/misc.o: In function `zlib_updatewindow':
  misc.c:(.text+0x190): undefined reference to `memcpy'
  misc.c:(.text+0x190): relocation truncated to fit: R_M32R_26_PLTREL against undefined symbol `memcpy'
  make[5]: *** [arch/m32r/boot/compressed/vmlinux] Error 1

by adding our own implementation of memcpy().
