Print out the libstdc++ version
Adding some quick code to print the version of the libstdc++ library that the to-be-tested compiler is going to use to the compiler-compatibility testing script
To help narrow down the supported range, it looks like GLIBCXX: 20120920 succeeds, but 20120313 fails.
It doesn't look to work well on ICC - the versions on the cluster I have access to are all printing 20110627, despite giving very different results for stdlib-dependent tests.
