Add CHANGELOG entry for #1336

Add a CHANGELOG entry for pull request #1336, which added added the
SkeletonBuilder::reference_obj() method to enable generated skeletons to
only reference instead of embed an object file. Doing so can reduce the
size of the skeleton potentially dramatically, and improve compilation
times along the way.
