Except this doesn't actually add those things into your image, it only ensures
they are built alongside it. To actually add them to the image you need to
ensure you add them to IMAGE_INSTALL; see:

If you want all -staticdev packages in the SDK for the libraries in your
image, add the following to your local.conf (or the image recipe, doesn't
matter which):

 SDKIMAGE_FEATURES = "dev-pkgs dbg-pkgs staticdev-pkgs"

If you want a single staticdev package in the SDK you'd need to add the
following instead:

 TOOLCHAIN_HOST_TASK_append = " simple1-staticdev"
