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.

4a142953ea Use current UID for initramfs root user:group 
Set the CONFIG_INITRAMFS_ROOT_{U,G}ID kernel variables to the current
user, so that all files end up being owned by root in the final
initramfs image.

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.
