eab95ea467 buildroot: copy KENRNELNAME files to $(KDIR) 
In order to support building both normal and initramfs kernel, we will
rebuild the wrappers around the vmlinux ELF binary, copy these with an
appropriate extension when they exist.

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)

97af76a920 include: calculate md5sum over sorted kernel config symbol list and incorperate it into the kernel metapackage version, make kmods depend on this specific version. The aim of this change is to invalidate kmods which are built against a different kernel config on the opkg metadata level. Manual copying and insmod of custom *.ko files, e.g. for development purpose, is still possible.

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.
