Faliure building unregistered GHC: pprGlobalReg: Unsupported register: CCCS

Hi,

the 7.4.1 release candidate failed to build on arm; previous versions built fine. It would be great if arm support would not be dropped, if it can be helped:

ghc-stage1: panic! (the 'impossible' happened)

Please report this as a GHC bug:  http://www.haskell.org/ghc/reportabug
