We don't want to have two separate library "ways" for SMP and single-
 threaded.  Unfortunately SMP requires an extra field in each thunk, which
 is a performance loss (<5%).

 In order to make it practical to use SMP, we will have to bite this
 bullet, however.

 With this change, -smp will be an RTS way only, just like -threaded.
