commit 508a3a33988d2872f580d8b727036f7f443d8b6d
Author: Thomas Miedema <thomasmiedema at gmail.com>
Date:   Thu May 28 19:34:15 2015 +0200

    Build system: don't build runghc if GhcWithInterpreter=NO (#10261)
    
    To test:
      * run `make clean` in utils/runghc
      * make sure inplace/bin doesn't contain runghc
      * set GhcWithInterpreter=NO in build.mk
      * run `make`
      * note that inplace/bin doesn't contain runghc
    
    It won't be installed either, nor will runhaskell.
