c++/5859: gdb fails to break in C++ MPI code

[Julian C. Cummings]

Actually, I was able to resolve the problem.  I filed a
bug report on the gdb debugger.  Someone responded to that
bug report and told me to update to version 2.12 of GNU ld.
Using the newer version of the loader resolved the problem.
Thank you for following up with my bug report.

Regards, Julian C.
