If I now understand correctly, the symbols present in updated versions of libgcc that are not in the "stock" system libgcc on darwin - need to be mentioned in the stub libraries (ligcc_s.10.{4,5,...} ). The emutls ones were not present causing linkage failures that were silently UNSUPPORTING a lot of tests.

No, those files are meant to describe what was shipped in the past on darwin as part of darwin. So, changing them isn't quite the right way to do this. Best to put them in the libgcc.a file and let them link in statically. Is there some reason why this doesn't work? I can answer questions and offer advice, feel free to cc me.
