+Subject: [PATCH] generateBuildIDs: Fix error handling.
+
+commit e6bdf7 made it so that we don't give a warning or error message
+for non-kernel ET_REL object files with missing or bad build-ids. But
+we still (unintentionally) failed generateBuildIDs which made us skip
+generating the cpioList causing an obscure failure message.
+
+Move the sanity check earlier so we don't process such object files at
+all. And if there is any real error from generateBuildIDs give a clear
+error message and explicitly set processingFailed.
