[meta-freescale] [meta-fsl-ppc][PATCH 1/2] ipc: use KBUILD_OUTPUT to point to build-artifacts

[ting.liu at freescale.com]

From: Liu Ting-B28495 <ting.liu at freescale.com>

In poky commit 46cdaf1, the kernel build output was put into
kernel-build-artifacts, and kernel-source is kept "pristine".

KERNEL_PATH points to kernel-source, while KBUILD_OUTPUT points
to build-artifacts which can be used for external module build.

ipc Makefile tries to include the .config, use KBUILD_OUTPUT to
avoid build error.
