Comment (by nomeata):

 > We probably should have merged that configure check into ghc-7.10 but
 it's water under the bridge now.

 JFTR, the configure script made it into ghc-7.10.3, at least I can see it
 at
 {{{
 checking for llc-3.4... /usr/bin/llc-3.4
 checking for opt-3.4... /usr/bin/opt-3.4
 checking whether bootstrap compiler is affected by bug 9439... no
 checking if llvm version is affected by bug 9920... yes

 configure: error: in `/«PKGBUILDDIR»':

 #9920.
