Adapting to differently named boost libraries

[springmeyer]

Boost libs sometimes have -mt at the end to signify they are the multithreaded versions. After Project-OSRM/osrm-backend@4a3db7e node-osrm now needs to link all dependent libraries so we need to know their exact name.

So, builds against homebrew based boost will start failing at 1c51388 until we come up with a solution.

Possibilities are:

• depend on OSRM to provide a pkg-config that provides all library names
• come up with some custom node-osrm script to find and detect boost library names

I think pkg-config is ideal, just need to start testing this post Project-OSRM/osrm-backend@8383222

work in progress at #28.

@DennisOSRM - after merging can you test the build against homebrew libraries? (I don't use homebrew currently for boost).

#28 seems to be working for me with homebrew.

thanks for testing @jfirebaugh - closing this now as #28 has landed.
