I think I have found the problem.
The kexec-tools build system is a bit unusual,
and the new file, kexec-pe-zboot.h, was not included in distribution
tarballs. Thus the build failures.
I think you can resolve that by squashing the following into this patch.
diff --git a/include/Makefile b/include/Makefile
