either the issue wasn't present until now (no arch hardconding in
BuildRequires before FC5), or nobody noticed.

I've been through this some time ago and had to give up. The cleanest
way would be for rpm to no hardcode these values but to always
evaluate them. E.g. have rpm -qRp ignore the require tags in the
header and reparse the specfile. But that's too invasive of a change
to fix something only nitpickers and buildsystems notice ... :/

I guess the only workaround is unpack-repack:

rpm -i --nodeps funny-1-2.src.rpm
rpmbuild -bs --target myarch funny.spec
</ugly>

The resulting src.rpm will be arch-specific for the target platform
containing the "real" BuildRequires.
