[fedora-arm] Running autoreconf for aarch64 support, why ?

Hi, While working on my Fedora packages, I noticed that %configure replaces config.guess and config.sub with /usr/lib/rpm/redhat/config.guess and /usr/lib/rpm/redhat/config.sub, ie: + for i in '$(find . -name config.guess -o -name config.sub)' ++ basename ./lib-src/libresample/config.guess + '[' -f /usr/lib/rpm/redhat/config.guess ']' + /usr/bin/rm -f ./lib-src/libresample/config.guess ++ basename ./lib-src/libresample/config.guess + /usr/bin/cp -fv /usr/lib/rpm/redhat/config.guess ./lib-src/libresample/config '/usr/lib/rpm/redhat/config.guess' -> './lib-src/libresample/config.guess' + for i in '$(find . -name config.guess -o -name config.sub)' ++ basename ./config.sub + '[' -f /usr/lib/rpm/redhat/config.sub ']' + /usr/bin/rm -f ./config.sub ++ basename ./config.sub + /usr/bin/cp -fv /usr/lib/rpm/redhat/config.sub ./config.sub '/usr/lib/rpm/redhat/config.sub' -> './config.sub' + for i in '$(find . -name config.guess -o -name config.sub)' ++ basename ./config.guess + '[' -f /usr/lib/rpm/redhat/config.guess ']' + /usr/bin/rm -f ./config.guess ++ basename ./config.guess + /usr/bin/cp -fv /usr/lib/rpm/redhat/config.guess ./config.guess '/usr/lib/rpm/redhat/config.guess' -> './config.guess' So why do we need to run autoreconf to update these, if they are replaced anyways ???
