Does that apply to symbols like __aarch64_ldadd4_relax? AFAICT, these are only discovered after LTO completes, which is the origin of the issue.
There's a bit of logic to handleLibcalls() before the link, but only if the libcalls are supplied via bitcode themselves, but not if they're provided via object files, as in the test case.
