Masahiro Yamada 4bd04b2037 sh: Remove compiler flag duplication
Every compiler flag added by arch/sh/Makefile is passed to the
compiler twice:

$(KBUILD_CPPFLAGS) + $(KBUILD_CFLAGS) is used for compiling *.c
$(KBUILD_CPPFLAGS) + $(KBUILD_AFLAGS) is used for compiling *.S

Given the above, adding $(cflags-y) to all of KBUILD_{CPP/C/A}FLAGS
ends up with duplication.

Add -I options to $(KBUILD_CPPFLAGS), and the rest of $(cflags-y)
to KBUILD_{C,A}FLAGS.
