linux-yocto-custom: provide defconfig guidance
As reported by Andrea, defconfigs created with savedefconfig should specify their expansion mode as "--alldefconfig' for custom yocto recipes. To ensure that this is documented, we can add a comment in the skeleton recipe.

+# defconfig: When a defconfig is provided, the linux-yocto configuration
+# uses the filename as a trigger to use a 'allnoconfig' baseline
+# before merging the defconfig into the build.
+#
+# If the defconfig file was created with make_savedefconfig,
+# not all options are specified, and should be restored with their
+# defaults, not set to 'n'. To properly expand a defconfig like
+# this, specify: KCONFIG_MODE="--alldefconfig" in the kernel
+# recipe.

# example configuration addition:
# SRC_URI += "file://smp.cfg"
