if you are using GNU tools there is some magic to make them
garbage-collect all the symbols in your executable before outputting the
final code. you have to do some tricks with the segment headers so that
it can GC individual functions but this should fix many of the image
size problems at least in some cases. I agree that the GHC image sizes
are a problem.
