kexec for powerpc mpc83xx processors

Hi,

Actually, I have posted two emails, one for mpc83xx compilation error and
other for mpc85xx support to mailing list.
I have got response only for mpc85xx email. Anyway, the compilation problem
is common for both mpc83xx and mpc85xx.
Sorry for inconvenience created by me..

I have changed subject to "mpc83xx" instead "mpc85xx", and continue compile
error in this email.
I will post new request for "support of kexec for mpc85xx", if required.

"Makefile.libfdt" file is not present in the package.

I have used following link to download package.
http://www.kernel.org/pub/linux/kernel/people/horms/kexec-tools/testing/kexec-tools-2.0.2-rc1.tar.gz
