kbuild: split final module linking out into Makefile.modfinal I think splitting the modpost and linking modules into separate Makefiles will be useful especially when more complex build steps come in. The main motivation of this commit is to integrate the proposed klp-convert feature cleanly. I moved the logging 'Building modules, stage 2.' to Makefile.modpost to avoid the code duplication although I do not know whether or not this message is needed in the first place.

kbuild: move modkern_{c,a}flags to Makefile.lib from Makefile.build Makefile.lib is included by Makefile.modfinal as well as Makefile.build. Move modkern_cflags to Makefile.lib in order to simplify cmd_cc_o_c in Makefile.modfinal. Move modkern_cflags as well for consistency. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

kbuild: preprocess module linker script There was a request to preprocess the module linker script like we do for the vmlinux one. (https://lkml.org/lkml/2020/8/21/512) The difference between vmlinux.lds and module.lds is that the latter is needed for external module builds, thus must be cleaned up by 'make mrproper' instead of 'make clean'. Also, it must be created by 'make modules_prepare'. You cannot put it in arch/$(SRCARCH)/kernel/, which is cleaned up by 'make clean'. I moved arch/$(SRCARCH)/kernel/module.lds to arch/$(SRCARCH)/include/asm/module.lds.h, which is included from scripts/module.lds.S. scripts/module.lds is fine because 'make clean' keeps all the build artifacts under scripts/. You can add arch-specific sections in <asm/module.lds.h>.
