From 0c00c3fb4e4a6ff714b7ad864f58e0fb33b3534c Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Wed, 23 Sep 2015 12:33:57 +0200 Subject: tools build: Add test for missing include The current build framework fails to cope with header file removal. The reason is that the removed header file stays in the .cmd file target rule and forces the build to fail. This issue is fixed and explained in the following patches. Adding a new build test that simulates header removal.
