[Cook] recursive descent cook problem

[Jerry Pendergraft]

I use patterns like:
%1/obj/%2.o : [match_mask %%0%2.c [project_files]]

or even (to have multiple compilers)
%1/obj/%2/%3.o : [match_mask %%0%3.c [project_files]]

And for binaries 
%1/bin/%2/%3 : [addprefix %1/obj/%2/ [%3_objs]]

You define you architectures (platforms), compiler, and products:
architecture_list = a1 a2 a3;
products = p1 p2 p3;
compiler = gcc;

Then your targets are:
programs = ;
  loop local thisarch = [architecture_list]
  {
      programs += [addprefix [thisarch]/bin/[compiler]/ [products]];
  }

And cook will automatically figure out which objects it needs to build and
will do so using the .o recipe.
