 Building some Debian packages on powerpc with GHC 7.8.4 fails as shown in
 this [https://buildd.debian.org/status/fetch.php?pkg=haskell-wai-app-
 static&arch=powerpc&ver=3.0.1-3&stamp=1431236338 build log], e.g.:
 {{{
   ghc: /usr/lib/haskell-packages/ghc/lib/powerpc-linux-ghc-7.8.4/unix-
 time-0.3.5/libHSunix-time-0.3.5.a: unhandled ELF relocation(RelA) type 252
 }}}

 I'm no PPC ABI expert, but I think the attached patch against master
 (which applies equally to 7.8.4) is reasonably plausible, and it at least
 allows wai-app-static to build cleanly.
