LOCAL_LIBS is meant to do.  Also remove the bad example of passing
preprocessor flags in CXXFLAGS from duneproject.

 * Adapt superlu-dist.m4, parmetis.m4, hdf5.m4, dune/common/test/Makefile.am
   and duneproject to the MPI changes.

 * Add DUNE_CHECK_LIB_EXT, a wrapper around AC_CHECK_LIB which allows to set
   the library path.

support for out-of-source builds in Dune.

You call dunecontrol with a parameter --builddir=NAME
dunecontrol will create a subdirectory NAME inside each 
module and do an out-of-source build there.

Not necessarily all modules support out-of-source, but at 
least common/istl did work.

  - Introduce autoconf substitutions DUNEMPICPPFLAGS, DUNEMPILDFLAGS and
    DUNEMPILIBS.
  - Deprecate MPI_LDFLAGS and MPI_CPPFLAGS: the automake manual recommends
    against "_" in names of such variables, MPI_LDFLAGS actually contains
    mainly libraries and simply changing MPI_LDFLAGS to MPI_LIBS will probably
    break a lot of stuff.  By deprecating MPI_CPPFLAGS it is possible to make
    the preprocessor generate a deprecation warning with instructions to
    change both MPI_CPPFLAGS and MPI_LDFLAGS (though this has yet to be
    implemented).
