Why not simply state the target using the (appropriately named) Target project attribute and then build using gprbuild? We use Target and Runtime attributes and it works like a charm:

project xyz is

   for Languages use ("Ada");

   for Target use "leon3-elf";
   for Runtime ("Ada") use "ravenscar-full-leon3";
   ...

end XYZ;

Are these two attributes not supported by FSF GNAT (yet)?

We have moved our development from using gnatmake to gprbuild and we have never looked back. It simply works.
