Comment (by luite):

 Side note: Hardcoded constants are also used for the target platform,
 while the actual target is configurable through `DynFlags`/`Settings`.
 Unfortunately properly printing a platform triple appears to be a bit
 hairy. I don't need this for GHCJS, so I've left it out so far for this
 reason.
