More precisely it comes from redhat-rpm-config which overrides rpm's own 
%configure macro.

Yup, and all wonderfully mixed up - rpm's idea of --target is something 
completely different from what auto*foo from this century thinks of it. 
Dunno if it ever was really valid but certainly not anymore.

rpm >= 4.8.0 no longer sets the --target on %configure but that's been 
masked by the redhat-rpm-config version of %configure. That's been fixed 
too as of today.
