Comment:

 @tibbe yes, we have been moving in that direction, in particular a GHC
 build contains all the native code generators, with the one exception that
 the choice between x86 and x86_64 is still a compile-time decision.  A lot
 of the work that Ian has been doing lately is heading towards making the
 backend a runtime decision, but there's still some way to go.
