For the application object files to get properly placed in the outdir when the source files are outside of the zephyr tree we need to set $srctree in kbuild to the parent dir of the application source code rather than getting the default of $srctree being set to $ZEPHYR_BASE. By doing this we are able to get the kbuild system to place the object file results in the outdir rather than in the application source dir.
