Yes, it seems like we could change the handling of LDPR_PREVAILING_DEF_IRONLY (and LDPR_PREVAILING_DEF_IRONLY_EXP I think) to be the same as LDPR_PREVAILING_DEF in the below switch statement. that would change linkonce_any/odr to weak_any/odr and keep the symbol. Let me try that and will update this patch.
