Bug#555714: mpich2: Please add support for blcr

[Pavan Balaji]

We had a short discussion on this within the MPICH group. We believe  
that we will be able to modify the code such that enabling it at  
configure time should not add any additional performance overhead for  
applications that don't need this support. So starting mpich2-1.3, you  
should be able to configure it in by default.
