Comment 0 for bug 1808318

This test passed with 4.18.0-12 on the last cycle [1]
But failed with the proposed 4.18.0-13 this time.

Test failed to build because of a missing include file:
50. ../../lib.mk:20: ../../../../scripts/subarch.include: No such file or directory

Tried to reproduce this cycle with 4.18.0-12 first and this can be reproduced as well.
