Likewise, s390(x)-ibm-linux are working fine now:

Um?  This does have the libstd++ results ...

It would appear the problem is this patch:
2005-05-12  Mark Mitchell  <mark@codesourcery.com>

        2005-04-04  Mark Mitchell  <mark@codesourcery.com>
        * testsuite/Makefile.am (check-local): Remove.
        (curent_symbols.txt): Likewise.
        (check-abi): Do not depend on current_symbols.txt.
        * testsuite/Makefile.in: Regenerated.
        * testsuite/libstdc++-abi/abi.exp: Build current_symbols.txt.
        2005-04-01  Mark Mitchell  <mark@codesourcery.com>
        * testsuite/Makefile.am (noinst_PROGRAMS): Remove.
        (site.exp): Write out the path to the baseline file.
        (check-abi): Use DejaGNU.
        (check-abi-verbose): Remove.
        * testsuite/Makefile.in: Regenerated.
        * testsuite/abi_check.cc (main): Check the return value from
        compare_symbols.
        * testsuite/testsuite_abi.cc (compare_symbols): Return a value.
        * testsuite/testsuite_abi.h (compare_symbols): Adjust prototype.
        * testsuite/libstdc++-abi/abi.exp: New file.
        2004-03-19  Phil Edwards  <phil@codesourcery.com>
        * testsuite/Makefile.am (site.exp):  New target, based on that
        created by automake.  Also set libiconv.

While using DejaGNU for check-abi might be a good idea in principle, the way
it is currently set up means that the 'make check-abi' run will overwrite the
libstdc++.log and libstdc++.sum files generated by the main 'make check' run.
This is why the results are missing from the test_summary report ...
