Are you using the toolchain native to debian stretch? There's a "oh goodness, nobody wants to deal with that" known issue with the hostboot linker where it doesn't deal with certain types of relocations even though it should. That being said, it looks like Luis has been doing some work fixing up all of the compiler warnings (and failings like this) for Hostboot with more recent GCC, so perhaps Luis can point you to the commits that fix it, as certainly open-power/op-build#2803 seems to indicate that this may be something fixed in recent hostboot.

Are you using the toolchain native to debian stretch

Yes. Didn't have a problem with it last year, though I note Debian changed enough to break an existing Yocto project in that same timeframe.

I'm compiling this from the latest hostboot master and a very recent op-build. I also went back to GIT hash 676c584 to see if it was a recent breakage due to the new weak symbol code, unfortunately it still fails the same way.

EDIT: Recompiling now with the linked GCC8 patch. Let's see if that fixes anything before trying to diagnose further.

I can confirm open-power/op-build#2803 resolves this issue

Ahh excellent. Hopefully we can get that all upstream soon.
