New description:

 When an installation of GHC doesn't include the vanilla "way", GHC cannot
 be built from this existing installation of GHC:

 make[1]: *** No rule to make target
 `/packages/ghc_x86-7.8.3-10/.self/lib/x86/ghc-7.8.3/base-4.7.0.1/Prelude.hi',
 needed by `utils/hsc2hs/dist/build/Main.o'.  Stop.

 E.g. using the following mk/build.mk:
 {{{
     V = 0
     GhcLibWays = dyn
     SRC_HC_OPTS = -O -H64m
     GhcStage1HcOpts = -O -fasm
     GhcStage2HcOpts = -O2 -fasm
     GhcHcOpts = -Rghc-timing
     GhcLibHcOpts = -O2

     DYNAMIC_BY_DEFAULT = YES

     NoFibWays =
     STRIP_CMD = :
 }}}

 Steps to reproduce:
 1. build & install GHC using above configuration
 2. rebuild GHC using above configuration, --with-ghc pointing to the
 installation created in step 1
