I don't understand, why should libstdc++ be included into rtems
builts?
libstdc++ comes with gcc and is not part of rtems sources. Therefore
it is getting build when building gcc.

I guess your problem is originating from the make-exe rule in your
make/custom/<BSP>.cfg.

There is a known (and still unfixed) problem with the general
working principle of make-exe and c++, which for some strange reason
only shows with some permutations of multilib flags for some
targets.
You might try to add -lstdc++ to the make-exe rule in your <BSP>.cfg
(cf. make/custom/gensh2.cfg - the sh2 is known to suffer from this
problem).
