Probably what is happening is that the test script is failing to find the
shared libraries (this is a problem with the test suite).  You may be able
to work around this by adding $objdir/libraries/libstdc++ to the
search path before running the tests (on some platforms this is done
with LD_LIBRARY_PATH but I'm not sure what AIX uses).
