OK, now I've *actually* thought about this .... we can't just detect
clock_gettime if profiling is enabled, because on Linux, that would let
the user fall into a situation where they had profiling but broken
oplocks. We should never allow oplocks to be broken.

Unfortunately, I think that this means that we need a new configure
macro to test whether linking with librt implicitly links libpthread. If
it does, we can disable clock_gettime without disabling
--with-profiling-data.
