  * Yet another go at making gcc -B work properly on windows
  This time it should work on linux too! But more significantly
  it should work when the user specifies a particular gcc. It
  would be very bad if the user gave an alternative gcc but we
  still gave it -B for the lib files of ghc's gcc. This go is
  rather cleaner as it uses the new program post-conf system.
