Personally, I don't see that there is much to be gained by doing this.

It's not as if different parts of GRASS really are separate packages. 
Everything depends upon libgis, and much of it depends upon e.g. GDAL. 
So it's likely to be more reliable if a single configure script
considers everything as a whole.
