Build a SDK by using bitbake my-image-name -c populate_sdk.

This will build a SDK which contains the -dev packages for everything that
goes into your image.  If you want headers that are not in your image
usually then you can add them to TOOLCHAIN_TARGET_TASK in the image recipe:

TOOLCHAIN_TARGET_TASK_append = " libsomething.dev"
