scripts/kallsyms.c has a special --absolute-percpu command line
option which deals with the zero based per cpu offsets that are
used when building for SMP on x86_64. This means that the option
should only be passed in that case, so add a check for CONFIG_SMP.
Otherwise, per cpu variables are recorded as absolute quantities,
(which they are not under !CONFIG_SMP) and they are not relocated
under CONFIG_RELOCATABLE=y.
