Enable link time optimization

To enable link time optimization, several configures needs to be
changed:
1. Add -flto in Makefiles
2. Use C++17 to get inline constexpr
3. Use gcc-ar and gcc-ranlib to generate static library, otherwise it
   gets link errors.

Tested: Build OK and unit tests passes.
