Can we add something to the top level Makefile like the following:

MPC8641HPCN_36BIT_config \
MPC8641HPCN_config:    unconfig
         @mkdir -p $(obj)include
         @if [ "$(findstring _36BIT_,$@)" ] ; then \
                 $(XECHO) -n "... I Rock " ; \
                 echo "#define CONFIG_PHYS_64BIT" >>$(obj)include/ 
config.h ;\
         fi ;
         @$(MKCONFIG) -a MPC8641HPCN ppc mpc86xx mpc8641hpcn freescale

(also add this to MAKEALL)

The name could be better.
