Implement proper C++11 mode detection

Newer compilers have C++14 mode as default and package maintainers tend
to not specifying a C++ version when building a package, this causes
compatibility issues when (for example) qbt is compiled in C++11 and
dependency lib is in C++14. See issue #9485.

What this commit does:
1. Checks if compiler supports at least C++11
2. Checks if compiler is set in at least C++11 mode
