[v3] cleanup testsuite for newlib targets


Fixes for new testsuite entries on cross targets. Non-C99 targets don't have a lot of the necessary functionality for full C++ conformance, so the required API bits are not met. In this case, these test are now marked as unsupported.

This isn't necessarily optimal, but I'd appreciate it if people let me roll with this until the header work is done and I have a fuller understanding of how to do this long-term.

        * testsuite/21_strings/headers/cstdlib/functions_std.cc: Without
        C99 support, _GLIBCXX_USE_WCHAR_T not defined, so
        dg-require-c-std.
