Kbuild updates for v4.19

- verify depmod is installed before modules_install

- 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
