Cleanup in parallel section of nofib suite. The fibish fcts are ok, i.e.
std way should succeed, parallel way should build.
Parallel way has to be run by hand (problems redirecting stdout), so not
automatic check whether output is identical to the provided file.
Added a bunch of test prgs for GdH in distributed section. Still need
to be integrated into nofib build machinery (currently standalone Makefiles).
Modified Makefiles to work with a parallel build. Have to omit runtest for now.
