OK, I see it today as well.  The only change to libstdc++-v3 between
these two builds was for a port configuration...

I have uncovered the grand mystery.  27_io/istream_seeks.cc, not
27_io/istream_unformatted.cc, creates istream_unformatted-2.txt.
Since 27_io/istream_unformatted.cc is usually tested after
27_io/istream_seeks.cc runs successful, this has not been spotted
until 27_io/istream_seeks.cc failed due to a change in the compiler.

Under the naming convention of tests and the files they create, this
appears to be a bug.  I suspect that a test was split at some point.
