Allow default RTS options to be specified by linking in an object file which defines the symbol `ghc_rts_opts' to point to a string of RTS options. This is preferred to using defaultsHook(), if possible. Perhaps we could remove defaultsHook(). (won't work with DLL's; if we ever ressurrect them we'll have to deal with this somehow).
