Cleanup ARCH handling, reorganize AArch64 and Make.inc.

Browse source 
* Previously, behavior differed if the same value of `ARCH` was defined
  within `Make.inc` or defined on the command line.  Don't do that.

* Provide saner defaults for `ARCH` and `MARCH`, and more importantly,
  allow for the proper overriding of both.

* Split `AArch64` code further away from the other `arm` code.
