[PATCH 0/7] linux-custom recipe rework

[Cedric Hombourger <Cedric_Hombourger@mentor.com>]

The Linux kernel is packaged a bit differently between Debian variants
and in particular for the perf package(s) in Debian vs Ubuntu. Since
there is no way the kernel build scripts would ever get distro specific
support for building more than the kernel and headers, we need our own
build/packaging scripts. The approach is documented in the custom_kernel.md
file included in this patch series.

This changeset was tested against ci_build.sh and some images were booted
on hardware available here. No regressions were detected (to date).

It is probably a good time to seek comments on the changeset and ideally
get it merged before starting some of the work-packages such as getting
perf packaged for Debian and Ubuntu distros.

Cedric Hombourger (7):
  recipes-kernel/linux: make KERNEL_DEFCONFIG support in-tree defconfigs
  linux-mainline: fix stripping of .0 from the kernel version
  linux-mainline: update from 4.19.0 to 4.19.80
  linux-custom: add support for kernel config fragments
  linux-mainline: disable support for HFS to demonstrate use of config fragments
  buildchroot-host: install qemu-static to support hybrid cross-compiles
  linux-custom: rewrite to no longer depend on the kernel's builddeb
