See package_generate_ipkg_conf in package_ipk.bbclass, it's echo-ing things in 
destination files sequentially.

I've thought that we're not doing multi-sdk, so it shouldn't be a problem. 
Although if some build would need to do some images plus an SDK it might be 
invoking package_generate_ipkg_conf from several places.

Maybe we can merge it with package_update_index_ipk (or just invoke 
package_generate_ipkg_conf from there leaving the function itself)? Everything 
except package-index meta-recipe does

package_update_index_ipk
package_generate_ipkg_conf

anyway.
