--- Comment #1 from Michael Hudson-Doyle <michael.hudson at canonical dot com>

This not-thought-through at all patch:
diff --git a/gold/powerpc.cc b/gold/powerpc.cc
index b0d6a74bec..1ef8c47053 100644
--- a/gold/powerpc.cc
+++ b/gold/powerpc.cc
@@ -11092,10 +11092,6 @@ Target_powerpc<size, big_endian>::Relocate::relocate(
value = (stub_table->stub_address()
+ stub_table->plt_size()
+ ent->off_);
- if (size == 64
- && r_type != elfcpp::R_PPC64_REL24_NOTOC)
- value += (elfcpp::ppc64_decode_local_entry(ent->other_)
- + ent->tocoff_);
}
has_stub_value = true;
}
fixes the issue for me. I certainly don't know if it would have other bad
effects.
