It looks to me like the ELF toolchain is emitting a non-weak alias for the alternate symbol. We don't (currently) support that in Darwin (and it's pretty unlikely we will given ld64's atom rules). Therefore, I concur that the correct action is to have two tests - one for each ABI and run both tests on all targets.
