 Numerous ghci tests in the testsuite currently fail on ARM due to the lack
 of a `mkJumpToAddr` definition. These failures look like,

 {{{
 ghc-stage2: panic! (the 'impossible' happened)
   (GHC version 7.7.20130927 for arm-unknown-linux):
        mkJumpToAddr not defined for ArchARM {armISA = ARMv7, armISAExt =
 FPv3,NEON], armABI = HARD}

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

 As it turns out `mkJumpToAddr` is fairly straightforward to implement.
 I've done this in https://github.com/bgamari/ghc/tree/arm. This brings the
 number of unexpected failures in `tests/ghci` from 44 to 4. These four
 failures are segmentation faults that I need to look more closely at.
