I am trying to understand the circumstances that lead to the failure,
and it's been made harder due to the lack of information. After some
investigation, my guess is that you're getting some duplicate symbols
because linux-osdata.o" is already in srv_tgtobj. Is that correct?
If yes, this part of the patch is OK, obvious even (once explained!).

I don't understand, however, what difference adding linux-tile-low.o
makes in terms of build failure.  Again, I have been trying to figure
out what lead to the failure, and searched our recent past, but could
not find anything. I know the change makes complete sense, but if not
logically tied to the build failure you are mentioning, I think we
should, if nothing else, document that fact for future archival, and
also commit this part of the change separately.
