Comment:

 Aaaaaa never mind... from `configure.ac`:

 {{{
   if test "x$OS_STAGE0" != "xOSDarwin"; then
     BOOTSTRAPPING_GHC_INFO_FIELD([AR_STAGE0],[ar command])
     BOOTSTRAPPING_GHC_INFO_FIELD([AR_OPTS_STAGE0],[ar flags])
     BOOTSTRAPPING_GHC_INFO_FIELD([ArSupportsAtFile_STAGE0],[ar supports at
 file])
   else
     AR_STAGE0='$(AR)'
     AR_OPTS_STAGE0='$(AR_OPTS)'
     ArSupportsAtFile_STAGE0='$(ArSupportsAtFile)'
   fi
 }}}

 This certainly explains your problem (since you are on Darwin)...

 git blame points to 24746fe78024a1edab843bc710c79c55998ab134. I wonder if
 it is okay to remove this hack by now?
