Subject: Link with boost_chrono library on OSX

Compiling on my OSX 10.6 build machine, I get:

Undefined symbols:
  "boost::chrono::steady_clock::now()", referenced from:
      boost::cv_status boost::condition_variable::wait_for<long long, boost::ratio<1ll, 1000000000ll> >(boost::unique_lock<boost::mutex>&, boost::chrono::duration<long long, boost::ratio<1ll, 1000000000ll> > const&)in bitcoinrpc.o

Linking against the boost_chrono fixes the issue.

Windows builds already link against boost_chrono; Linux doesn't, but compiles (on pull-tester / gitian, at least).
