Bug#653616: libmpich2-dev: Missing library linkage for libmpich.so on MIPS(el) and S390

[Pavan Balaji]

The best method is to use pkg-config to find what libraries need to be 
linked in.  Currently, this list is libmpich, libmpl and libopa, if you 
are using generic TCP/IP and shared memory support.  But if you enable 
other modules, more libraries might be required.
