Hey Mattieu!

for old pvfs and lustre, add to LDFLAGS and LIBS when configuring mpich 
(and in turn, romio)

for pvfs2, ROMIO's configure looked for and used pvfs2-config to add the 
appropriate libraries and headers.  ROMIO would then add those to 
'src/mpi/romio/localdefs' so the needed libraries would propagate up to 
the mpicc wrapper.
