#     powerpc/boot: pass CONFIG options in a simpler and more robust way
#     
#     Commit 5e9dcb6188a4 ("powerpc/boot: Expose Kconfig symbols to wrapper")
#     was wrong, but commit e41b93a6be57 ("powerpc/boot: Fix build failures
#     with -j 1") was also wrong.
#     
#     The correct dependency is:
#     
#       $(obj)/serial.o: $(obj)/autoconf.h
#     
#     However, I do not see the reason why we need to copy autoconf.h to
#     arch/power/boot/. Nor do I see consistency in the way of passing
#     CONFIG options.
#     
#     decompress.c references CONFIG_KERNEL_GZIP and CONFIG_KERNEL_XZ, which
#     are passed via the command line.
#     
#     serial.c includes autoconf.h to reference a couple of CONFIG options,
#     but this is fragile because we often forget to include "autoconf.h"
#     from source files.
#     
#     In fact, it is already broken.
#     
#     ppc_asm.h references CONFIG_PPC_8xx, but utils.S is not given any way
#     to access CONFIG options. So, CONFIG_PPC_8xx is never defined here.
#     
#     Pass $(LINUXINCLUDE) to make sure CONFIG options are accessible from
#     all .c and .S files in arch/powerpc/boot/.
#     
#     I also removed the -traditional flag to make include/linux/kconfig.h
#     work. This flag makes the preprocessor imitate the behavior of the
#     pre-standard C compiler, but I do not understand why it is necessary.
