reproduce (this is a W=1 build):
wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
chmod +x ~/bin/make.cross
git remote add agd5f https://gitlab.freedesktop.org/agd5f/linux.git

Note: the agd5f/drm-next HEAD e35cc9020f7b4540f5fbbff9fbe08808aab9addc builds fine.
It only hurts bisectability.
