Makefile changes: BUILDCONF and CABAL_BKP.

+ Changed BUILDCONF to point to dist/setup-config, not .setup-config.
  This is where current versions of Cabal put it.  'make clean' works again!
+ Do not clean up CABAL_BKP, because it might need to be recovered for
  a new build with a different GHC version.
