It works correctly on Fedora 20 32-bit and 64-bit.
I don't actually know what the affected distribution is, which makes it hard. But it would be rather surprising if it didn't, since I suspect people would have noticed and complained very quickly and loudly if there was ever a glibc version that didn't work without a vDSO.
TBH, I'd be more surprised if this breaks anything than I'd be if current kernels are already broken.
