In the doodle I did years ago, I had a CROSS_BUILD_FLAVOR = {trivial, gnuconf, custom} and had that drive some of the infrastructure.  This didn't make it into the final hack we used at symmetricom, however.  Some of that can be inferred from other variables, but we didn't bother to try to build stuff we didn't need and that might not be working.
