Thanks for applying this patch, but it seems some files were missed while applying the patch. I can see that while the changes for Makefile.in where picked (please see <https://git.kernel.org/pub/scm/utils/kernel/kexec/kexec-tools.git/commit/> for details), the kdump directory is still present in the tree (please see <https://git.kernel.org/pub/scm/utils/kernel/kexec/kexec-tools.git/tree/kdump> for details).
