[Masahiro Yamada]

Hi Linus,

Please pull Kbuild updates for v4.17.


You will see a merge conflict in
arch/blackfin/kernel/bfin_ksyms.c

This file was already removed since
the blackfin support was entirely dropped.
So, please remove it.

----------------------------------------------------------------
Kbuild updates for v4.17

- add a shell script to get Clang version

- improve portability of build scripts

- drop always-enabled CONFIG_THIN_ARCHIVE and remove unused code

- rename built-in.o which is now thin archive to built-in.a

- process clean/build targets one by one to get along with -j option

- simplify ld-option

- improve building with CONFIG_TRIM_UNUSED_KSYMS

- define KBUILD_MODNAME even for objects shared among multiple modules

- avoid linking multiple instances of same objects from composite objects

- move <linux/compiler_types.h> to c_flags to include it only for C files

- clean-up various Makefiles
