Title: Fix threading detection for GCC 4.7+.

Threading support detection in Boost 1.48.0 is broken against GCC 4.7+. Patch pulled from trunk. See https://svn.boost.org/trac/boost/ticket/6165 for more info.

Though GCC 4.2.x shipped in XCodes is unaffected, it is still helpful for people with hand built GCC from upstream. Thanks.
