commit: 15105f5f068efaadc15936bc92da3f9d0a260ce2 [121/198] Kbuild: always define endianess in kconfig.h
config: h8300-h8300h-sim_defconfig (attached as .config)
compiler: h8300-linux-gcc (GCC) 7.2.0
reproduce:
wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
chmod +x ~/bin/make.cross
git checkout 15105f5f068efaadc15936bc92da3f9d0a260ce2
# save the attached .config to linux build tree
