389-ds-base and freeipa on 32 bit arches

Greetings gcc maintainers! A FESCo issue[0] has been filed due to the dropping of 389-ds-base and freeipa on 32 bit arches for Fedora 28. This was done without a change request being filed, so FESCo is trying to decide how best to handle it. It seems there are some concerns about whether the C tooling correctly handles some cases for 32-bit arches that led to the decision by the IPA maintainers to drop support for 32-bit. FESCo would like to ask for the GCC maintainers' input on the issue. Thanks in advance for your feedback! [0] https://pagure.io/fesco/issue/1845 [1] https://bugzilla.redhat.com/show_bug.cgi?id=1544386
