Due to PrelException_PutFullMVar_static_closure there is a circular
dependency between libHS and libHSrts, which is broken during the
linking phase by mentioning -lHS again *after* -lHSrts. Hmmm, perhaps
it would be better to mention the smaller -lHSrts twice instead? With
this patch 4.06 can build 4.07, now let's see if it bootstraps...
