 I'm having trouble figuring out what I do to add support.  I'm getting
 this when building my qnx-nto-arm cross-compiler on head:

     ghc-stage1: panic! (the 'impossible' happened)
       (GHC version 7.9.20140929 for arm-unknown-nto-qnx):
             globalRegMaybe not defined for this platform
