The patch changes nothing related to any particular target. If I were to hazard 
a guess I would think the tests are linking against a wrong version of the 
library, the follow on patch (not yet committed) is bumping the libgfortran 
major version number.

I do not have access to a target machine unless there is a way to remote in.  Is 
there one in the gcc compile farm?
