This comes from the rpm %configure macro, which hasn't changed:

  ./configure --build=%{_build} --host=%{_host} \\\
        --target=%{_target_platform} \\\

%{_host} is set by the rpm package in the macros file, %{_build} defaults
to the value of %{_host}. %{_target_platform} comes from --target on
the command line, plus the usual vendor/OS bits

--target is what is set by rpm/mock. I think it defaults to %{_host}
if it's not otherwise specified, but we specify it when building for i686,
as we could theoretically still build i386 packages.
