commit: 80591e61a0f7e88deaada69844e4a31280c4a38f kbuild: tell sparse about the $ARCH
date: 8 months ago
config: alpha-randconfig-s031-20200710 (attached as .config)
compiler: alpha-linux-gcc (GCC) 9.3.0
reproduce:
wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
chmod +x ~/bin/make.cross
# apt-get install sparse
# sparse version: v0.6.2-37-gc9676a3b-dirty
git checkout 80591e61a0f7e88deaada69844e4a31280c4a38f
# save the attached .config to linux build tree
