Whilst I'd agree with you over that, how about something like the following patch:
===8<=== CUT ===>8===

That then allows one to do...
Q> make arch makefile Q> make arch dep clean modules modules_install bzImage
...and one actually gets asked which architecture one requires. However, if one omits the "arch" from those lines, it just uses the native architecture.
Best wishes from Riley.
