Good question. "--target" will primarily change the way certain macros 
are defined, so it all depends on if and how those are accessed by the 
spec file... In this case, it looks like the "configure" macros from 
/usr/lib/rpm/macros are used, which I'd normally say is the right way to 
do it, but the default "platform" setup looks a bit weird. You may want 
to try

rpmbuild --rebuild --target=mips-linux-gnu --define "_build mips-linux-gnu" ./x.src.rpm
