[boost] Multiple link definitions on Darwin tests

Recently, many of the Darwin tests started failing. A bunch of them 
were the new
serialization tests, and I've been working with Robert Ramey to 
figure out why and fix them.

However, I have come to realize that a lot of the failing tests are 
not in the serialization library.

Before I start debugging this myself, does anyone have any suggestions?

For example, _all_ the program options tests are failing, with messages like:
<http://boost.sourceforge.net/regression-logs/cs-Darwin-links.html#program_options-cmdline_test-darwin>

>program_options - cmdline_test - darwin
