kbuild: resync top Makefile, mkmakefile, tags.sh with Linux 5.7-rc4
The prologue of the build system is not specific to Linux or Barebox.
Paritially resync with Linux 5.7-rc4
- In Linux, $(objtree) is always '.', and $(srctree) might be relative.
I am keeping both absolute for now to avoid unexpected breakage.
- I did not resync single target for now. We need to touch
Makefile.build a lot if we want to resync it.
- 'export CDPATH=' is Barebox-only code, which was added by
commit 6cc8d0544658 ("Makefile: disable CDPATH"). Keep it.
- KBUILD_SRC no longer exists in the upstream Linux. I replaced it
with building_out_of_srctree.
- scripts/mkmakefile does not contain anything specific to Linux or
Barebox. Resync it with Linux 5.7-rc4
- scripts/tags was imported from Linux 3.6 with some cherry-picks on
top of that. Resync it with Linux 5.7-rc4
