Rebuild benchmark sources when Makefile is updated

Benchmark programs are generated using parameters from the Makefile,
so it is necessary to rebuild them whenever the parameters in the
Makefile are updated.  Hence, added a dependency for the generated C
source on the Makefile so that it gets regenerated when the Makefile
is updated.
