powerpc: convert makefiles to Kbuild style
Note:
arch/powerpc/cpu/mpc8260/Makefile is originally like follows:
---<snip>---
START = start.o kgdb.o
COBJS = traps.o serial_smc.o serial_scc.o cpu.o cpu_init.o speed.o \
---<snip>---
COBJS-$(CONFIG_ETHER_ON_SCC) = ether_scc.o
---<snip>---
$(LIB): $(OBJS)
$(call cmd_link_o_target, $(OBJS) $(obj)kgdb.o)
The link rule `$(call cmd_link_o_target, $(OBJS) $(obj)kgdb.o)'
is weird.
kbdg.o is not included in $(OBJS) but linked into $(LIB)
and $(LIB) is not dependent on kgdb.o.
(Broken dependency tracking)
So,
START = start.o kgdb.o
shoud have been
START = start.o
SOBJS = kgdb.o
That is why this commit adds kgdb.o to obj-y, not to extra-y.
