 Trying to build yesod platform on Samsung Chromebook (architecture is
 armv7l), and get this crash in compiling the package vector-0.10.0.1:

 [ 5 of 19] Compiling Data.Vector.Fusion.Stream.Monadic (
 Data/Vector/Fusion/Stream/Monadic.hs,
 dist/build/Data/Vector/Fusion/Stream/Monadic.o )
 ghc: panic! (the 'impossible' happened)
   (GHC version 7.4.1 for arm-unknown-linux):
         Cant do annotations without GHCi
