Whoever built this GCC should read https://gcc.gnu.org/wiki/InstallingGCC

The -L option is redundant, GCC knows how to find its own libraries,
you don't need to tell it where they are.

The -lstdc++ option is only needed because you are linking using gcc,
linking using g++ will do that automatically. See
