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.
