[Fedora-packaging] Fix problems building Extras packages for FC3 and FC4

Hi! Now that mock on the Extras builders was updated to 0.6 (thx dgilmore for your work) we noticed that there are big problems building Extras packages for FC3 and FC4. For details see this thread: https://www.redhat.com/archives/fedora-extras-list/2006-August/msg00091.html The problem is well know and described in #196930 -- opened by Paul Howarth on 2006-06-27 We really should fix this as soon as possible. That means: - add elfutils to the default buildroot in all Fedora Dists < FC5 - add python to the default buildroot in FC3 and FC4 Everyone (especially fedora-packaging) fine with that? I'd like to see this fixed soon and would like to avoid waiting for the next meetings. If yes: can somebody (skvidal) please apply this patch: https://bugzilla.redhat.com/bugzilla/attachment.cgi?id=133705 and update http://buildsys.fedoraproject.org/buildgroups/ please? The patch does what's described above and also fixes the default buildroots for older dists (see patch for details). CU thl
