Comment(by heisenbug):

 This is the panic:
 {{{
 ghc-stage1: panic! (the 'impossible' happened)
   (GHC version 7.7.20130412 for powerpc-montavista-linux):
         expectJust initTcInteractive
 }}}
 It happens (presumably) just after the `.hi` file is written:
 {{{
 $ rm libraries/integer-simple/dist-install/build/GHC/Integer/Type.hi
 $ rm libraries/integer-simple/dist-install/build/GHC/Integer/Type.o
 $ make libraries/integer-simple/dist-install/build/GHC/Integer/Type.o
 stage=1 V=0
 }}}

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

 Looking at the build products, only one of them is present:
 {{{
 $ ls -l libraries/integer-simple/dist-install/build/GHC/Integer/Type.o
 libraries/integer-simple/dist-install/build/GHC/Integer/Type.hi
 ls: libraries/integer-simple/dist-install/build/GHC/Integer/Type.o: No
 such file or directory
 -rw-r--r-- 1 ggreif rts 16699 Apr 15 12:27 libraries/integer-simple/dist-
 install/build/GHC/Integer/Type.hi
 }}}
 Second attempt is successful:
 {{{
 $ make libraries/integer-simple/dist-install/build/GHC/Integer/Type.o
 stage=1 V=0
 }}}
