Thank you for this report! I just pushed a fix:
https://git.kernel.org/pub/scm/linux/kernel/git/sj/linux.git/commit/?h=damon/next&id=bbc588c9166d6ff4ac9b270929732760215a94c3
Reproducing the error on my own failed as below, though, so I was unable to
verify the fix on my own. Please let me know if anything wrong.
$ COMPILER_INSTALL_PATH=$HOME/0day COMPILER=gcc-8.5.0 ~/lkp-tests/kbuild/make.cross W=1 O=../linux.out/ ARCH=arc SHELL=/bin/bash mm/
Compiler will be installed in ~/0day

There was a silly typo, sorry. Pushed another fix for that:
