Not sure I understand what you are saying here.

If a buildd succesfully compiles code which does *not* request any ARMv6 
or ARMv7 features (e.g. hardfloat or neon), then is there any problem at 
all?!?

If you really want, you can add a build rule to explicitly fail, but 
please elaborate why that would be necessary.

Nothing need to happen with those, I believe.
