 Head fails on powerpc64le:
 {{{
 ghc-stage1: panic! (the 'impossible' happened)
   (GHC version 8.7.20181103 for powerpc64le-unknown-linux):
         PPC.CodeGen.getRegister: no match

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

 libraries/ghc-prim/ghc.mk:4: recipe for target 'libraries/ghc-prim/dist-
 install/build/GHC/PrimopWrappers.o' failed
 }}}

 I think I know what is going on and will work on a fix.
