Fix a bug of kexec load on x86_64. Kexec fails to do load on x86_64, with
error message:
Symbol: cmdline_end not found cannot set
Because kexec/arch/i386/kexec-bzImage.c accesses cmdline_end symbol in
i386 purgatory, but there is no cmdline_end in x86_64 purgatory, and
kexec-bzImage.c is used by x86_64 too.
cmdline_end is added into x86_64 purgatory to solve the bug, because kexec
jump support for x86_64 is planned.
