Sanchayan Maity 0f4b39775c Fix splash2 benchmark
During the last commit of splash2 benchmark it seems before committing
when we ran "make clean", it effectively undid what the patch at below
link did
http://www.capsl.udel.edu/splash/Download.html

Fix this since without this it is not possible to build the arcane
splash2 benchmark.
