  The Fedora policy is to build on the target architecture IIRC,
and that's probably a good idea before delivering a final build that
all packages be rebuilt that way for sanity and self hosting guarantee.
However for the initial stage of getting a set of packages build,
finding and solving issues that's probably the right approach, as
it will be way faster I think and easier to run. But it should be
made clear which rpms where build with cross compilation
(the rpm BuildHost info is probably sufficiant but that should be
tracked).

 my 2 cents
