kerneldev: create kernel-devsrc packaging
kernel-devsrc is responsible for creating and a packaging an environment
appropriate for kernel development (on or off target).
To create this support, we only need to copy/install the results of the
virtual/kernel providers build in the staging dir ... with some minor
manipulations to the source tree (.git removal and a clean up). This
produces a source tree that is capable of rebuilding the kernel on the
target.
Installing the kernel-devsrc package on a target (along with a
toolchain) is all that remains to be done.
$ cd /usr/src/kernel
$ make oldconfig
$ make -j2 bzImage
