When calling "make sdk" we also sanitize the staging tree. Therefore "sdk" must depend on all packages. Sanitizing staging is not really needed, in the sense that any rpath in there is simply not going to be used. We want to sanitize staging for the following reasons: - To avoid leaking references to the original output directory. This way, we can validate that the SDK is relocatable by running a simple "grep -r ${BASE_DIR} ${HOST_DIR}". Obviously RPATH sanitization is not sufficient (e.g. also the references to source files have to be stripped), but it's a step in the right direction. This reason is obviously only relevant for the SDK. - To make sure that when an executable is copied to target that it actually executes correctly. Since within Buildroot we never copy stuff from staging to target, this is clearly only relevant for the SDK.
