When LINKER=$(CXX) you do not "link with a C++ compiler" you still link with
the linker, ld, but the g++ driver passes it additional libs including
-lstdc++. That means you can't fine-tune which libstdc++ is used, defeating the
purpose of --with-host-libstdcxx. To allow fine-tuning the libs, you need the
additional libs to not be used, which implies not linking with g++.
If you use --with-host-libstdcxx then you need to get the argument right.

No, it's not equivalent, -static-libstdcxx does not imply -lstdc++, which is
why you get missing symbols.
Why not just use the Sourcery configuration that works?
