This comes from the rpm %configure macro, which hasn't changed:
./configure --build=%{_build} --host=%{_host} \\\
--target=%{_target_platform} \\\
More precisely it comes from redhat-rpm-config which overrides rpm's own
%configure macro.
%{_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.
Yup, and all wonderfully mixed up - rpm's idea of --target is something
completely different from what auto*foo from this century thinks of it.
Dunno if it ever was really valid but certainly not anymore.
rpm >= 4.8.0 no longer sets the --target on %configure but that's been
masked by the redhat-rpm-config version of %configure. That's been fixed
too as of today.
