[Buildroot] [PATCH v2, 1/2] boost: context needs thread if gcc <= 4.6

mutex is available on gcc 4.7.x, the issue is that boost does not
correctly detect it because -std=c++11 is missing.
Keep thread select for gcc version lower or equal to 4.6

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
