Because the build machinery doesn't know that it's a 32 vs 64
bit thing.  All it knows is that it's yet another multilib.

Anyway, how are you going to tell if your ultrasparc can't run
a 64 bit binary?  Certainly all of them are capable, given the
right os/kernel combination.  I'll suggest trying to run it is
the only foolproof way of detecting whether it can be run.
