The existing kbuild system has generic rules for building .o from .S
but generic rules do not work with special flags, separate source and
object etc. so kbuild 2.5 does not use generic rules. pp_makefile4
builds the global makefile with explicit rules for what is required,
including deciding how to convert C or asm to object.
pp_makefile4 only generates make rules if the object is selected. I am
guessing that you have hard coded head_8260.o in the link commands for
zvmlinux. Objects to be linked must be selected under the same
base_target(), like this from i386.
base_target(bzImage)
select(bbootsect.o bsetup.o)
user_command(bzImage
($(objfile bbootsect) $(objfile bsetup) $(objfile compressed/bvmlinux)
$(objfile tools/build))
(set -e;
$(OBJCOPY) $(OBJCOPYFLAGS) $(objfile compressed/bvmlinux) $(objfile
compressed/bvmlinux.out);
cd $(objdir);
tools/build -b bbootsect bsetup compressed/bvmlinux.out $(ROOT_DEV) > $(@F))
()
)
