fix test for HAVE_QUAD on some instances of ubuntu 13.10

Browse Source 
I haven't figured out why this happens, but on one of my computers
running kubuntu 13.10 g++ says the following if one tries to use
quadruple precision math:

/home/erne/src/ewoms/ewoms/common/quad.hh: In static member function ‘static quad std::numeric_limits<__float128>::min()’:
/home/erne/src/ewoms/ewoms/common/quad.hh:52:14: error: unable to find numeric literal operator ‘operator"" Q’
     { return FLT128_MIN; }

since this happens only on this machine and only with the c++ (but
not the C) compiler, i suppose that this is either an upgrade issue
with kubuntu or an issue with the ubuntu gcc stack. Strangely enough,
my other kubuntu machine does not have a problem with that...

In any case also testing for assignability of constants and using the
C++ compiler for the quadmath test won't hurt...
