BFS: Set -std=c++11 in bfs_shell c++flags for gcc >= 3

Required for use of non-static data member clang complains about this line in CheckVisitor.cpp: memset(&Control().stats, 0, sizeof(check_control::stats)); some explination: https://stackoverflow.com/questions/29359661/clang-error-invalid-use-of-non-static-data-member http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2253.html Referencing a non-static data member inside a struct was retroactively made undefined in C++98 and only allowed on C++11 even though gcc permits the code to compile. No change to functionality intended.
