When kbuild executes, the following steps are followed (roughly):
1) Configuration of the kernel => produce .config
2) Store kernel version in include/linux/version.h
-3) Symlink include/asm to include/asm-$(ARCH)
-4) Updating all other prerequisites to the target prepare:
+3) Updating all other prerequisites to the target prepare:
- Additional prerequisites are specified in arch/$(ARCH)/Makefile
-5) Recursively descend down in all directories listed in
+4) Recursively descend down in all directories listed in
init-* core* drivers-* net-* libs-* and build all targets.
- The values of the above variables are expanded in arch/$(ARCH)/Makefile.
-6) All object files are then linked and the resulting file vmlinux is
+5) All object files are then linked and the resulting file vmlinux is
located at the root of the obj tree.
The very first objects linked are listed in head-y, assigned by
arch/$(ARCH)/Makefile.

and builds the final bootimage.
- This includes building boot records
- Preparing initrd images and the like
