Comment (by erikd):

 The `configure` script in `bindistprep/ghc-7.11.20150402` contains:

 {{{
     if test -z "$LlcCmd"
     then
       SettingsLlcCommand="llc"
     else
       SettingsLlcCommand="$LlcCmd"
     fi
     if test -z "$OptCmd"
     then
       SettingsOptCommand="opt"
     else
       SettingsOptCommand="$OptCmd"
     fi
 }}}

 and niether `LlcCmd` not `OptCmd` variables are set anywhere. Obviously,
 that is no longer sufficient.
