Do you need c++?

If not, just remove "--enable-cxx" from the configure call above
(rtems++ won't be built then). 

If you need c++, read on below.

cpp is the C-preprocessor
g++ is the C++-compiler

So, the symlink is wrong.

I think you missed to build and install <target>-g++.

Add c++ to the list of languages being passed to configure when
configuring gcc/newlib:
configure ...
