Feels to me that this is working around a problem instead of fixing the problem. This happens for -tiny-initramfs because the root fs contains a populated /dev tree, with device nodes in. There is no hard association between "has a static /dev" and "SDKs are meaningless", so a better fix would be to remove /dev from the SDK entirely, instead of removing SDKs from one image, when this is a general problem.

Currently, if we do `bitbake core-image-tiny-initramfs' and then install the generated SDK, the following error appears. tar: ./sysroots/core2-64-poky-linux/dev/console: Cannot mknod: Operation not permitted The populate_sdk task does not make much sense for this recipe and considering the fact the its SDK cannot be installed, we'd better just delete the task.
