[tex-live] x86_64-linux: libstdc++

[Martin Schröder]

Hartmut's binaries for x86_64-linux have a dynamically linked
libstdc++. This is a problem, as we learned years ago:
> ldd ./xetex
./xetex: /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.9' not found
(required by ./xetex)
        libfontconfig.so.1 => /usr/lib64/libfontconfig.so.1 (0x00002b7b30635000)
        libstdc++.so.6 => /usr/lib64/libstdc++.so.6 (0x00002b7b30778000)
        libm.so.6 => /lib64/libm.so.6 (0x00002b7b30979000)
        libgcc_s.so.1 => /lib64/libgcc_s.so.1 (0x00002b7b30acf000)

Hartmut, how did you manage to beat --with-cxx-runtime-hack ?
