No libstdc++ for nvptx.
The C++ front end insists to link against libstdc++ -- which we don't build:
$ < build-gcc/gcc/testsuite/g++/g++.log grep -o 'error opening [^[:cntrl:]]*' | sort | uniq -c
2 error opening libasan.a
2 error opening libssp.a
12075 error opening libstdc++.a
Based on GCC trunk r220892:
