a402b5c48d build: make sure modules are modposted after initramfs image is built 
Otherwise the modpost steps for individual modules that are compiled
manually (using make package/<name_of_module>/install) will give warning
of missing symbols when that module depends other modules.

This is caused by the Module.symvers file not containing any symbols
anymore of external modules when the initramfs image is built without
specifically giving the modules target.

c77feae6be include: Clean-up kernel git command options management 
The way git options are managed in kernel-defaults.mk makes additions

difficult. If requires different code path for each option; it's
ok so far as we handle only one option, but if we want to make the git
clone mechanism more flexible, more option will be required, which
will become tedious.

So; we'll move the GIT options into a variable, that may or may not be
set depending on the configuration, and we'll pass this variable to the
git command.

45e3540a3f config: Remove KERNEL_GIT_LOCAL_REPOSITORY option 
The GIT_LOCAL_REPOSITORY option adds the --reference argument to the
git clone kernel command line, if KERNEL_GIT_CLONE_URI is set.

This option is intended to speed-up the repo creation by using local
objets rather than downloading it. However, a local repo can be cloned
much faster by setting GIT_LOCAL_REPOSITORY directly to the local tree.

In that case, git clone will bypass the normal "git aware" transport
mechanism and clone the repository by copying and hardlinking objects
rather than downloading it, resulting in a significant speed increase.

That makes the GIT_LOCAL_REPOSITORY option pretty useless so we'll just
remove it and recommand the usage of KERNEL_GIT_CLONE_URI directly.

76133009c9 sparse: add as a new package selectable from the config 
This change does multiple things, all related to enable sparse usage as
a static analysis tool selectable from the OpenWrt configuration:
*add a KERNEL_SPARSE option in the config to add sparse to the kernel
 build (through the C=1 option usage)
*add sparse as a new host tools. It will get selected automatically when
 the above option will be enabled

34ffb526a2 build: rework verbosity level selection 
V=99 and V=1 are now deprecated in favor of a new verbosity class system,
though the old flags are still supported.
You can set the V variable on the command line (or OPENWRT_VERBOSE in the
environment) to one or more of the following characters:

- s: stdout+stderr (equal to the old V=99)
- c: commands (for build systems that suppress commands by default, e.g. kbuild)
- w: warnings/errors only (equal to the old V=1)

881bac2db2 Allow targets to specify extra initramfs source files 
The CONFIG_INITRAMFS_SOURCE Kconfig variable can be a space-separated
list of source files (or directories). This allows a platform to
add extra components to the initramfs image, by defining the
INITRAMFS_EXTRA_FILES make var.

By default, we add a simple initramfs extra file for the generic-2.6
platform, which specifies a few device nodes.

4bb2c88f4e don't specify "CC=<nothing>" on kernel build command line 
If KERNEL_CC isn't set, we end up with a "CC=" on the kernel build
command-line. We don't always need CC, as the CROSS_COMPILE flag does
the job instead. In fact, specifying CC messes up the build when we're
using a biarch compiler.

This change doesn't specify CC= if the KERNEL_CC variable is empty.
