I'd much rather write this as a probe to see if linking with -rt makes a
difference, and only add it when it matters, than trying to blindly add
it (the pre-patch version) or to blindly exclude it for some platforms
(the post-patch version). I also wonder if gnulib has some help on this
front. NACK to this version while I investigate.
