reproduce:
  wget https://git.kernel.org/cgit/linux/kernel/git/wfg/lkp-tests.git/plain/sbin/make.cross -O ~/bin/make.cross
  chmod +x ~/bin/make.cross
  git checkout 1b7bde6d659d30f171259cc2dfba8e5dab34e735
  # save the attached .config to linux build tree
  make.cross ARCH=m68k

All error/warnings:

   drivers/net/ethernet/freescale/fec_main.c: In function 'fec_enet_rx_queue':
>> drivers/net/ethernet/freescale/fec_main.c:1470:3: error: implicit declaration of function 'prefetch' [-Werror=implicit-function-declaration]
