    build: Support (and prefer) libboost_thread-mt
    
    Google's libphonenumber uses Boost.Thread but somehow fails to let their
    shared library to express that dependency. Therefore we must manually
    link with Boost.Thread. Now Fedora only installs libboost_thread-mt, but
    not libboost_thread. This patch checks for both build variants of the
    library and prefers libboost_thread-mt. The change in preference is
    because it doesn't make much sense to use a Boost.Thread variant that
    isn't thread-safe, does it?
