Switches that gnatmake needs to pass to gcc must be given as "-cargs <gcc_switches>" after at least the files to compile (see the gnatmake docs for all the subtleties). This commit makes that happen, in a way that triggers rebuilds only for things that actually depend on GNAT, and not the other compilers contained in GCC.
