Fedora requires builds on the target system (either native or emulated,
but not crossed) because:
* some builds do tests, which will fail in cross
* some builds make a mini-${FOO} and then execute that to build the
final ${FOO}, which will fail in cross
* BuildRequires must sometimes be of the same arch as the target (e.g.,
libraries) and sometimes of the same arch as the builder (tools) --
there is no way at present to know which is which, so it's a requirement
that target arch == build arch
These can be overcome, but not without massive retooling.
