Package: gnat-4.9

The libgnatprj build uses an ugly combination of the just built g++ together
with system c++ header files.  This may work for a native build where the
dependency is fulfilled by the g++-4.9 build dependency, but it complicates
cross builds and builds from the same source.  Please use the header files from
the just built libstdc++.

It looks like this can be done by respecting CC, CXX, CFLAGS and CXXFLAGS set by
the toplevel Makefile.

The toplevel Makefile.def also seems to missing a dependency on libstdc++-v3 for
libgnatproj.

I verified that this does indeed solve the problem.

OTOH, AFAICT, libgnatprj.so is not linked and does not use any symbols
from libstdc++ so does not need a dependency on it.
