You are right, we seem to not check the note originator name and assume it is "GNU" if we don't recognize it. This needs fixing in ebl_object_note and ebl_object_note_type_name. Proposed a patch upstream:
commit 58ec17dbc828160f46c9bb4bc7ab97b44ac6b8fc
Author: Mark Wielaard <mjw>
Date: Fri Feb 12 15:04:00 2016 +0100
libebl: Don't assume ELF notes are "GNU" when unknown, recognize "Go" notes.
We used to assume any unknown ELF note provider name was "GNU" and didn't
recognize any of the "Go" provider types. We now check the provider name
explictly in ebl_object_note_type_name and recognize the following Go
note names: PKGLIST, ABIHASH, DEPS and BUILDID. But there is no attempt
yet in ebl_object_note to decode the description of these notes.
