I can confirm having this:

ld --version
GNU ld (GNU Binutils; openSUSE Tumbleweed) 2.29.0.20170830-0

Now I'm given correct result for my small sample:
g++ main.c -ltest -L. -flto -O2 --save-temps && grep xyz main.res
232 224d00cabf975876 PREVAILING_DEF_IRONLY_EXP _ZZ3goovE3xyz

However I still have problem with the libstdc++ example:

$ grep storage pr82172-2.res
1310 caa2dce973a8949f PREVAILING_DEF_IRONLY _ZNSs4_Rep20_S_empty_rep_storageE

Can you please test it?
