sp4 uses 32-bit compilation and MPI and is an evolution of the old set of 
flags from the NPACI bluehorizon.
sp4+mpi uses 64-bit compilation and MPI

the other two sp4 versions are for non-parallel 32-bit and 64-bit 
compilations.

MASS is IBM's accelerated math library (containing faster but slightly less 
accurate calls to math functions). There is also libmassv (which we do not 
link to) that does vectorized calls to math functions.

The /usr/local/apps/mass path was left in there so that the file is still 
useful on the NPACI bluehorizon. libmass.a is installed in the standard 
directories for bluesky so despite /usr/local/apps/mass not existing on 
bluesky the library is found and linked in.
