I wish I had time to do that, but I really do not have time to sort how to determine that reliably, also people have been pretty upset if anything in the build changes lately and anything breaks.  So I am very afraid to touch any defaults.

Due to time and the pressure to not break anything I can do one of two things:
1) clean up the two targets I've submitted and put them in a Makefile.cross-install, then document them in the main Makefile.
2) Keep this code in my own repo.

Sorry.  Let me know if there is a way forward with 1 for the time being?
