Here's the logic I'm using now in my build-and-test script;
I think this works for all versions of gcc >= 2.95.
(This is still easier to understand than how 'make check'
works, but just barely...)

# gcc-2.95 called the c++ library libstdc++.
# gcc-3.[0123] called the c++ library libstdc++-v3.
# gcc-3.4 calls the c++ library libstdc++, but it still lives in the libstdc++-v3 directory, grumble.
# See http://gcc.gnu.org/ml/libstdc++/2003-08/msg00034.html
if test -d $TARGET/libstdc++-v3; then
    LIBSTDCXX_DIR=libstdc++-v3
    if test -f $BUILD_DIR/$GCC_DIR/libstdc++-v3/testsuite/lib/libstdc++.exp; then
       LIBSTDCXX_TEST=libstdc++
    else
       LIBSTDCXX_TEST=libstdc++-v3
    fi
elif test -d $TARGET/libstdc++; then
    LIBSTDCXX_DIR=libstdc++
    LIBSTDCXX_TEST=libstdc++
else
    abort "can't find libstdc++ or libstdc++-v3"
fi

...

cd $TARGET/$LIBSTDCXX_DIR/testsuite
runtest --tool=$LIBSTDCXX_TEST --target=$TARGET -v || echo Some $LIBSTDCXX_TEST test failed...
