[patch] SSAR application - add capability to read little-endian files on big-endian systems

[Don McCoy]

The default behavior with this patch is to keep the present behavior and
assume that no byte swapping should take place when reading files from
disk on little-endian systems (the files in the apps/ssar/set1 are in
little-endian format). 

On big-endian systems, the bytes will be swapped into the correct order
by default.  In either case, the user can override this behavior by
using the new switches "-swap" and "-noswap".

It also fixes a minor error in header file location and a path error in
the makefile that occurs only when 'prefix' is /not/ used (hence the
reason we didn't notice it).

Ok to apply?
