  * Toggle whether the RTS gets build with debugger support for ghci
  
  Specifically, this disables the special support in the RTS for looking up the datacon name corresponding to an address. 
  Correspondingly, the debugging commads in GHCi will not be available, and neither will the '-fdebugging' flag
