Without this flag, mutex is not always correctly detected with gcc 4.x
or 5.x. As a result, boost_thread is wrongly selected by boost_context.

Fixes:

Changes v1 -> v2 (after review of Thomas Petazzoni):
 - Update first patch to keep selection of boost-thread but lower gcc
   version from 4.8 to 4.7
 - Update second patch to add -std=c++11 only if gcc >= 4.7
