Merge tag 'kbuild-v4.19' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild

Pull Kbuild updates from Masahiro Yamada:

 - verify depmod is installed before modules_install

 - support build salt in case build ids must be unique between builds

 - allow users to specify additional host compiler flags via HOST*FLAGS,
   and rename internal variables to KBUILD_HOST*FLAGS

 - update buildtar script to drop vax support, add arm64 support

 - update builddeb script for better debarch support

 - document the pit-fall of if_changed usage

 - fix parallel build of UML with O= option

 - make 'samples' target depend on headers_install to fix build errors

 - remove deprecated host-progs variable

 - add a new coccinelle script for refcount_t vs atomic_t check

 - improve double-test coccinelle script

 - misc cleanups and fixes
