I might go so far as to suggest that the benefit of avoiding that
%if "%{_arch" == "%{_build_arch}" stuff in the specfile might outweigh
the extra dependencies on autoconf and sed, too.

One way of handling dependencies in mock for cross-builds might be to
install the full set of dependencies for _both_ host and target
architectures.
