Because linking c++ is more than adding -lstdc++.

... no. Using g++ for linking performs other g++-internal tasks, such as
composing ctors/dtors lists for static constructors and to pull in
further (g++-internal) libraries into linking (cf. collect2 in newer
gcc's).

What it exactly does is highly target- and gcc-version depending. It can
boil down to "just adding -lstdc++", but in most cases it will perform
more.
