make sure that flags passed with DUNE_LDFLAGS are the first flags in linker test and not duplicated another time.

[Merge][Bugfix] r7422 from branches/release-cmake-2.2: Prevent definition of HAVE_BOOST without value due to race conditions i
n some autoconf versions.

For some autoconf versions there was a race condition between ax_boost_base.m4 a
nd dune_boost_base.m4 resulting in HAVE_BOOST being defined with no value (inste
ad of ENABLE_BOOST). For others there were even two definitions of it (one with 
and one without value). 

This patch renames the symbol being defined in dune_boost_base.m4 to HAVE_DUNE_B
OOST and defines a value for it if boost is found.

Previously there still was a dependency to build the pdf which miserably failed as we don not distribute tex files.

Here is Andreas' commit message:

Subject: [PATCH] once again: fix dune_unused.m4

my previous attempt was only partially correct: the compiler did not
chocke because the unused attribute was placed behind the variable,
but because the third argument of AC_TRY_COMPILE is placed inside the
main function. it seems like c++ does not support nested functions, so
the test still failed, leading to the equally undesired result that
DUNE_UNUSED did not have an effect anymore. Mea culpa!

(this time I have at least double verified, that the compiler does not
bail out. last time I probably mis-interpreted the wrong lines as the
output of the dune_unused test in config.log.)
