Thanks, I've verified that setting `RelaxELFRelocations` in `TargetOptions` indeed works around the issue. I'm a bit concerned about what other compatibility issues this will cause though. If I understood correctly, relax relocations is a relatively recent feature and not compatible with older linkers, so may not be a suitable compiler default.
