  builddeb: split libc headers deployment out into a function
(2020-01-29 01:51:30 +0900)

----------------------------------------------------------------
Kbuild updates for v5.6

 - detect missing include guard in UAPI headers

 - do not create orphan built-in.a or obj-y objects

 - generate modules.builtin more simply, and drop tristate.conf

 - simplify built-in initramfs creation

 - make linux-headers deb package thinner

 - optimize the deb package build script

 - misc cleanups
