This patch allows each project to have a private linux build.
Split build of kernel headers and kernel image into two source trees. Kernel headers are built in $(TOOL_BUILD_DIR) Kernel build is in $(PROJECT_BUILD_DIR) Make sure that kernel patches are applied to the kernel tree in $(PROJECT_BUILD_DIR) Add board specific patches, if available.
