Comment (by aosivitz):

 Hm, so- as I understand it. We create a single libghc_XX.dylib for use by
 TH, which in turn references each of its dependencies and loads them with
 'load commands' (of which there is a hard total size limit on MacOS).
 What's the reason we take this step instead of just loading each
 dependency directly? Is that also for performance? If so, could we
 generate two of these libghc_XX.dylibs? Or 1 per every 50 dependencies?
