 symlink would have to point to the wrapper script that invokes the GHC
 binary, so the cleverness might have to be in the script, not GHC itself.

 Oh, right, because we still need to pass the right -B flag. So symlinks
 won't work for runghc, as the #! line will still point to a script.

 So I think that that reduces our options to either leaving things as they
 are, or requiring that people use `#!/usr/bin/env runhaskell` if they want
 to make Haskell scripts.
