Update the NAME version tweak example patch for the
newer kernel. This moves the example to the 4.2 stable
kernel and appends -custom to the VERSION string.

The kernel development manual recommends making a copy of
linux-yocto-custom, while the comments in the recipe talk about
bbappends.
To synchronize the two, we remove the bbappend references from the
recipe and instead indicate that a copy should be updated.

It was pointed out that the kernel development documentation recommends
making a copy of linux-yocto-custom, while the comments in the recipe
itself suggest a bbappend.
To keep things consistent between these two sources, we update the
comment in the recipe itself to also recommend a copy (and rename).

As reported by Andrea, defconfigs created with savedefconfig should specify
their expansion mode as "--alldefconfig' for custom yocto recipes. To ensure
that this is documented, we can add a comment in the skeleton recipe.

The Yocto kernel tools look for SRCREV_machine in do_validate_branches,
if it's empty, it just returns and silently continues. This likely needs
at least a warning. However, this recipe should be using SRCREV_machine,
and not just SRCREV.

It is necessary to supply file://defconfig to the SRC_URI when using
a defconfig (it is not implicitly understood as the commentary might
currently suggest).

There has been some confusion over proper use of the linux-yocto-custom
recipe. It is not intended to build as is from meta-skeleton. It should
be modified via a bbappend file to provide a Linux kernel config at the
very least.
Update the commentary to make this requirement more explicit. Add some
additional detail about how to create a bbappend file and how and when
to modify the various variables.
Clear COMPATIBLE_MACHINE so bitbake will not attempt to build the recipe
unless the user explicitly adds there machine to the variable, which
should encourage them to read the recipe comments before attempting to
build it.

Remove the linux-tools include as perf is now packaged independently.
Without this, including meta-skeleton in bblayers.conf results in a
build failure as linux-tools.inc cannot be found.

Adding a skeleton/refrence recipe for using a subset of the yocto
kernel tools against kernel git repositories.
Sample/reference configuration fragments, features and a patch are
provided and documented in the recipe.
From the recipe itself:
Provides an example/minimal kernel recipe that uses the linux-yocto
and oe-core kernel classes to apply a subset of yocto kernel
management to git managed kernel repositories.
Notes:
kconfig(s): the kernel must be configured with a defconfig, or via
configuration fragment(s). Either of these can be added
via bbappend.
patches: patches can be merged into to the source git tree itself, added
using standard bbappend syntax or controlled via .scc feature
descriptions (also via bbappends)
example configuration addition:
SRC_URI += "file://smp.cfg"
example patch addition (for kernel v3.4 only):
SRC_URI += "file://0001-linux-version-tweak.patch
example feature addition (for kernel v3.4 only):
SRC_URI += "file://feature.scc"
Warning:
Building the sample kernel tree (kernel.org) without providing any
configuration will result in build or boot errors. This is not a bug
it is a required element for creating a valid kernel.
