I only did some basic testing of the hard-float abi.  Bell SW has offered to do more extensive testing
as part of this JEP.

I have no way of knowing if any of the other profiles are being used but I would think it’s
worth keeping them in the event that someone wants to try to build/test these other configurations.

The goal of this JEP is to eliminate the arm64 port and not cause any other changes in behavior.
