[Dune] dune-grid on trunk does not compile when ALUGrid is not enabled

[Steffen Müthing]

Dear Dune,

the current trunk of dune-grid currently does not compile without ALUGrid. The problem
is in dune/grid/alugrid/2d/Makefile.am: The variable libalu2d_la_SOURCES is set to
nothing when ALUGRID is not enabled. This causes my automake (1.11.1) to emit a
link command with no object files specified, which in turn causes ar to fail (This is on
OS X, I have no idea what Linux ar does in this case). I fixed it temporarily by adding and
linking to an empty dummy.cc to that directory (unfortunately, the nodist_EXTRA_*_SOURCES
trick doesn't work there), but I don't think that is really a solution...

As a side note, the LDFLAGS and LIBADD variables in that file refer to the 3d version
of the library. Was that intended?

Thanks for your help,

Steffen
