Also add the GL flags to the ALL_PKG_* variables.

 * 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.

  variables.
* Use that infrastructure to war about MPI_CPPFLAGS.

  - 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).

#define HAVE_MPI ENABLE_MPI

ENABLE_MPI is defined in the MPI_CPPFLAGS as ENABLE_MPI=1 if and only if
MPI was found by configure.

  fixes bug #23

- added theoretical support for GCC with IBM MPI: the options (which
  are tailored toward xlc) are changed a bit. However the following
  problem remains: ./configure adapts the test programs to the
  C++ compiler it find. Thus, a test program passed to mpCC fails
  because the implicitly used xlC doesn't understand the line meant
  for g++... Maybe this (and a whole lot of other problems) just
  vanish if xlc 7.0 is used so I'll do nothing about it

On the other hand the new mpiCC offers parameters to extract the flags
without passing dummy-names which is used if LAM >= 7.1 is found
