When an header file is removed, or more often when bisecting or more generaly when we checkout an older version where some header file didn't exist yet, we typically have generated .d files containing dependencies on a non-existing header file. In this case, make abort and complains about the dependencies that can't be met. Avoid this situation by using the '-MP' option so that GCC can automatically add a dummy rule for those header file.
